XCore's EduBook, a Netbook That Runs on AA Batteries
I'm typing this on a netbook with no hard drive, not using a chip from Intel or AMD, and powered by AA batteries. Eight rechargeable AAs, to be precise, in a bank of cells right where a Li-Ion battery would sit in a conventional laptop. The batteries charge in place, too (regulation prevents overcharging) meaning that the power cord is a simple three-prong-to-cloverleaf cord, no wall-wart required. It's the EduBook from Xcore (see that page for some photos of the internals, too), and it's a cool concept. Despite some warts, it's one of the most interesting things I ran into on the CES show floor last month (Xcore's Michael Barnes kindly supplied the laptop, straight from the display case). Read on for my review.
Yes, it runs Linux.
Before diving in to anything else, note that this is a laptop built for running Linux; the one I'm using is running Ubuntu 9.4 (Jaunty), and others that I played with briefly on the show floor were running instead Barry Kauer's lightweight (around 100MB by default) Puppy Linux. Though Puppy's quite a nice OS, I stuck with Ubuntu on the EduBook, because that's what I'm most used to.
Why 9.4, now nearly a year out of date? Because a few bits of stock Ubuntu caused hiccups, which Barnes blames on packaging goofs by Ubuntu. Xcore has tweaked the default drivers to get working two important subsystems -- networking and sound. (Puppy Linux apparently works on these fronts just as supplied.) Until I know that an upgrade won't result in a disconnected and mute machine, I'm sticking with what works. (Other distributions, including Ubuntu derivative Linux Mint, are reported to work well, too.)
Purpose, Philosophy, and Ingredients
The EduBook is what you might get if you gave the OLPC team a simpler mandate in their quest to provide laptops suitable for educational use: it's small, cheap to produce (currently, the retail price for this 512MB RAM/8GB SD version is about $200, depending on order size), fairly sturdy, modular, and upgradable — after a fashion. And like the OLPC project's XO, it's intended as an educational tool, and for distribution in places around the world where computers have long been too expensive to be common. To that end, the company's shipped machines (besides "quite a few" to the US, Canada and Mexico), to South America, Asia, the Middle East, and six countries in Africa (Nigeria, South Africa, Ghana, Tanzania, Ethiopia, and Uganda).
Modularity means the EduBook can be readily assembled inside or outside of an importing country, which can make a huge difference in the local price of a computer because of the vagaries of import duties and other taxes. Some countries charge higher import duties for importing un-assembled computer parts, though often the opposite is true. According to Barnes, "Indonesia now allows people to import computers with no tax. Thailand does as well. However, in both countries, they will apply taxes on the components if you bring them in as components. Both countries have programs where you can build in tax free zones and export but if you import the parts to assemble and sell locally, it is cheaper to buy it already assembled."
The machine's guts are made for flexibility. Unlike the all-in-one approach of Intel's Centrino line (incorporating wireless as part of a motherboard+processor package), the EduBook uses a x586 system-on-chip core (block diagram) to provide processor, video and 512MB of main memory, but farms out wireless and storage; for wireless hardware, there's essentially a USB slot and a niche carved out of the motherboard. That way, the latest and greatest wireless interface (or the cheapest and most readily available) can be added at assembly time, keeping the three external USB ports free. Any USB wireless device small enough to fit will do -- it just has to work with the OS. (The company also runs a development and support site for working with the quirks of running a slightly offbeat processor.)
The EduBook is upgradeable, but not user upgradeable. Instead, the parts are modular enough that new chip generations, larger SD cards, or improved wireless modules can be readily swapped in by the maker (or by local manufacturers) while preserving all the user-facing parts (screen, keyboard, ports).
For storage, there's another (internal) slot for an SD card — an 8GB card in my sample — presented to the system as an IDE device. No conventional hard drive (though it is possible to order one in place of the SD card) means that the EduBook lags even typical low-end netbooks for raw storage capacity, and SD cards aren't the speed demons that SSDs are. But this isn't a machine built for carrying a road-warrior's movie collection or sticking into a data-center rack, and XCore86 have snipped out probably the most common failure point for laptops. (And SD cards are easier to source and simpler to replace than hard drives.) In practice, and considering that the system-on-a-chip processor is also aimed at frugality rather than speed, it's hard to fault.
The outside of the case is typical (but tough-seeming) netbook: the only port on the back is the AC inlet to power the laptop and charge the batteries; on the right side of the chassis are two USB ports; on the left, one more USB port, along with ethernet, a VGA out (which I didn't test), microphone and headphone jacks, and a 10/100 ethernet port.
Facing the user is a perfectly nice, perfectly standard, 1024x600 LED-backlit display. A Pixel Qi daylight-readable one would be nice; maybe one will show up in a future iteration.
Fit, finish, feel
The input devices on a laptop with 9" screen are small, of necessity — but for me, even a small keyboard beats a touchscreen or thumbboard. The keyboard is of the "nearly full size" variety. The touch-pad, also constrained by reality (about 2.5" x 1.5") is smooth and responsive — perhaps too responsive. My hands aren't big, but I've still had some curse-inducing frustration and backspacing at typing on this.
One problem I have with touchpads generally (and most laptops are saddled with them) is that an inadvertent tap of the thumb while typing can lead to an accidental cursor jump or text swipe -- and suddenly you're typing in the middle of the wrong paragraph or wiping out a chunk of what's already been written, and scrambling for Ctrl-Z. On the EduBook, this happens far more frequently than I'd like, though it's teaching me slowly to keep my thumbs hovering a bit higher. In use, and knowing that this is a machine built for other than high-end multimedia use, the twitchy keyboard and pointer are my biggest complaints. Another nitpick: the trackpad's buttons work, but they're chintzy, and ever-so-slightly misaligned, catching the skin on my thumb slightly when I move from left button to right.
The case seems strong — a little brick-like, even, at slightly more than an inch thick. The bottom of the case (not metal, but heavy-duty plastic) features two large areas of corrugation for an additional bit of rigidity. I am skeptical of Barnes's claim that it compares well with the durability of the OLPC XO, but that's a very high bar: the sturdy case and solid-state storage sure make it seem more drop-safe than my 10" Asus Eee or most other laptops I've owned over the last 18 years.
What's missing
Going in, I knew this was a small laptop built for getting online and as a tool for school kids, rather than a high-end machine (in which case I'd have a different set of complaints). Taking the EduBook on its own terms, though, I'd like to see a few things:
- Better Battery life indicator. Though the reader can gather from an LED at the front edge of the case whether the machine is charged, charging, or drastically low on charge, it would be nice to have a better-integrated on-screen indicator for remaining battery life.
- An external SD card slot. After first dismissing such a slot as a novelty, owning two laptops with built-in SD slots has spoiled me for the convenience. And on a storage-lean device like the EduBook, its absence is notable. An external SD slot would make this machine a lot more flexible.
- An easier system to change the batteries. The bank of AAs lives behind a small door secured by a pair of small Phillips-head screws. It's a small thing, but one reason I like AA batteries as a power source is that if you really needed to, it would be cheap to buy a few hours' worth of power, or to keep a spare set of Eneloops or other charge-retaining rechargeables around. (No heavier than the wall-wart you don't have to carry.) On the other hand, the batteries aren't soldered in place, and carrying a mini-Phillips driver around is no great burden. And, since this is a device intended for schools and children, the company has no intention to make the batteries or other internals easier to get at. Having accidentally tried to recharge some alkaline batteries recently (in a wall-charger, not the EduBook), I concede this has some merit.
- Working Suspend/Resume. The great bugaboo of Linux laptops raises its head here, too; shutting the lid or selecting Suspend from the Gnome menu triggers the error message that "Suspend is not available on this computer." A shame, when power savings are part of the overall appeal.
Performance, and the Takeaway
The 2000ma batteries in my sample gave me between 3 and 3.5 hours unplugged; that's about an hour less than the best performance I get from my Eee laptop's 4-cell battery, but still a respectable netbook battery life (though falling behind the new generation of all-day machines). Charging (until the light on the case indicated a full charge) took between 4 and 6 hours.
Wireless performance was quite good at Seattle coffee shops and in hotel rooms in Las Vegas and Portland, but I've hit an odd hitch: it's finicky on the (Apple-based) network at my home — I can see a fairly strong signal, but sometimes can't connect. (Gremlins?) An ethernet port on the side means I'm not totally out of luck.
The practical outcome of using a processor that's proudly taking up the rear of the performance curve is that startup takes over a minute (I timed 1:05 from hitting the power button to the Ubuntu login prompt, and another 45 seconds to a Gnome desktop). The low-power chip means that it doesn't do Flash either (no Facebook Scrabble for you!), but using the EduBook for most Internet tasks, typing notes, creating scripts or other light programming, and even using The GIMP is acceptably, usably quick. But note: applications work fairly well once they've started, but that startup can be a bit painful; more than a minute for OpenOffice, for instance. A faster chip would be nice (and bumps to the processor speed are expected), but as a connection to the Internet with a real keyboard and a decent screen, capable of running standard versions of word processors, programming languages, graphics packages and more, it strikes me as less obviously innovative but more flexible than OLPC's machines. It's impressive to me that an x586 can run Ubuntu and Gnome as well as it does; though there are lots of promising developments in the world of non-X86 chips, too, right now X86 is still the target architecture for the bulk of Linux distros, including ones built for education.
All of this means that the EduBook is slow, but useful, not just in its intended classroom application, but as a knockabout netbook generally.
Yes, it runs Linux.

If you RTFA, the thing gives you an option of using AAs, or Li-ion, as you see fit.
Should I be scared that the default country for the order form is Thailand?
Ah, you're that person companies have to write stupid shit like: "Don't get in the bath with this laptop", for indemnity, and because you're retarded.
If you RTFA
If I do that how the hell am I supposed to formulate a semi written out thought and get it submitted so it doesn't just look like I'm yelling out FIRST POST, without paying for it of course.
One thing that review did gloss over, but which is right there in TFA, among the first things listed.
"It can support Microsoft Windows XP."
So Linux is one of the options for this thing (they actually list a bunch of distros that work, apart from the one they specifically designed for the thing), not the only option.
Given the cries of how OLPC had sold out when they said they're going to support XP, I thought it would be kinda relevant...
I got one of these, and I were very surprised that it was covered here! I certainly don't think the case is very sturdy, a few millimetres plastic was easy to crack, and I've done that. I've got some evil pixels on the screen too after dropping it once. I got mine with ubuntu, but I managed to thrash X and have not taken my time to fix it, I use it on daily basis exclusively with vim, but being the CLI junky I am I almost like it more that way than with a gui. I carry it around for all my lessons in school and I'm very happy that I bought it. A little weird thing with it is that the usb ports are upside down, no clue if that's a feature or something stupid =p A big downside for me was that it is i586, something I didn't think off when buying it, meaning that distros such as Arch Linux won't run on it natively.
Form factor is almost irrelevant here. What matters is the following:
1) Can XCore continue to improve the SOC with higher clockspeeds and features?
2) Can the XCore86 CPU compete performance-wise with Atom?
3) For almost $200, how do they intend to compete against existing UMPCs from makers like Asus?
This EduBook is cute, but the question remains whether this SOC can truly compete against the Atom+US15W in the marketplace. Getting a free device because you're some hotshot Slashdot editor isn't quite the same thing as comparison shopping for the right solution.
You can buy a Lenovo S10 with 1GB of ram, 1.6Ghz CPU and 160GB harddrive for $249, and that includes WinXP.
The AA batteries sounds interesting, but since all the netbooks come with a battery, and they are cheap enough to buy an entire new netbook with new battery when anything breaks or wears out.
If this unit was $150 or less, it's slow CPU and AA battery power might make sense. But at $199 it's not worth it.
Did the first couple of spills do any damage?
Are you really that thirsty that you can't avoid dumping liquid on expensive electronics?
Nerd rage is the funniest rage.
I know you guys hate Apple for it, but there's a reason they're getting 8 hours out of a 17" laptop. It's because they threw away all the 'packaging' crap that comes with normal batteries and only packaged the 'energy storing' part.
So when it explodes you get more bang for your buck.
Ah, but if you RTFA, then you can make witty retorts to FIRST POSTS which get modded up in a shower of karma. Without paying, either.
As an embedded solution, an SD PHY would allow for the addition of Wifi pretty easily.
That's gotta be one of the longest press releases (written to be an review) that I've seen in a long time.
I wonder what it costs to have your ad run on the front of Slashdot as a story these days.
Serious? Seriousness is well above my pay grade.
AAs are typically charged in series by in-device chargers. That is significantly worse than single-cell chargers because small differences in the capacity of the single cells result in over-charging which kills the batteries. Li-Ion batteries on the other hand are always charged individually because they are actually dangerous when overcharged.
There isn't a good reason to use AAs for a device which goes through one charge in a matter of days, especially when an unsophisticated charger is used. What we really need is a standard Li-Ion rechargeable battery format.
See here for more info.
I have an older consumer digital camera made by sony that had rechargeable batteries that were AA's. Worked extremely well as long as I owned the camera. The nice thing was in a pinch, say a long day of pictures or forgetting to recharge the batteries, I could run into any store and grab a pack of AA and keep on going. Granted, only got about 3 hours of shooting time on 2AA's, but it was handy.
I imagine this would be the same way, some kind of rechargeable that are in the same form factor as AA and then you can pop in AA's in a pinch.

That's the most brazen Slashvertisement I've ever seen. The editors(writers, whatever) could have at least tried to obfuscate it into an article and offload the interested onto the actual website.
I'm still trying to decide whether to be disappointed that the editors no longer care, or happy that they're being more honest about blatantly slashvertising.
Direct AC connection? 110-240V? I don't know about you guys, but I ain't gonna put that damn thing on my lap. This is a laptop. I have spilled coffee, juice, other drinks on my laptops. I don't want 240V shock on my private parts. I let my young kids to use laptop too and certainly wouldn't allow this one to them.
Most likely the AC-DC power converter is sealed up. Take a look at a "wall wart" power supply sometime - do you see anywhere for liquid to leak in? Even my EEE's AC adaptor, which isn't sealed, also doesn't feature any openings into which liquid could readily flow.
And then, what do you think this combination of liquid and voltage is going to do, exactly? Is the voltage going to follow the liquid's electrical path out of the abundantly ground-planed environment of the power supply and computer, and follow a path up your arms, through your heart, and then back down to the computer to get to a ground path?
I'm not feeling too scared, really.
Bow-ties are cool.
I think we'll reach a new Slashdot low today where people won't even read the summary!

AAs are a horrible way to power a laptop. Why not power a car with them?
Last time I checked, a laptop wasn't an automobile.
And by your logic, AA batteries are a "horrible" way to power *anything*.
AAs are a horrible way to power a TV remote. Why not power a car with them?
AAs are a horrible way to power a phone. Why not power a car with them?
AAs are a horrible way to power a portable device. Why not power a car with them?
See how stupid it sounds?
because critics would have lambasted the "XCore E8"?
The name of the product is the Gecko EduBook. It is targeted for classroom use. If you are going to pass out 20 of these things to a classroom of students you are not going to have power cords running all over the place. You can buy AA batteries in bulk, and they are super cheep. It will cost around $1.79 to replace batteries in one of these things.
You sound pretty current with the what's-what in parenting, but what if they resist?
Hack it and install a DC power socket. Its only a cheap device after all. How about installing a three pin regulator while you are at it?

For me it is an unusually interesting slashvertisement so I think it belongs on the front page.

From TFA: "There is no bulky power adapter. The power supply is built inside the Gecko so that all you need to carry is a power cord."
I've had enough ATX power supplies and laptop power adapters go bad... one of the latter even threw sparks and smoke. Never damaged the actual computer, and they were all easy to replace.
The power adapter for my netbook is smallish, but bigger than I'd want embedded inside my netbook. And what about RF noise? What about safety? Sounds crazy, but I've had a waterfall (from a leaky roof) open right up on me while using a computer before. Once I even used a faulty laptop that shocked me when using it, annoying but not deadly.
I loved it. I'm sure it still works. I also have the acoustic (300 baud) coupler for the built-in modem.
Also, there's the Newton.
Some day maybe 2 week battery life will be back.
SD slot??? WHY??? How about just a USB reader and a USB port on the machine?
Then you can use SD, CF, microSD, xD, miniSD, MMS,...
If you look at the pictures: the SD slot is internal. It's one of the options for primary storage. I can only hope the thing has a very good SD card interface... The reason they included this slot is to provide a cheap way to configure the machine with solid-state storage. SD cards can't compete with good-quality SSDs, but it's very cheap to add an SD slot to a machine, the SD cards themselves are cheap and easy to find, and it doesn't take much physical space inside the machine.
I own a EEE 901 - personally I find the built-in card reader quite convenient. IMO it beats dragging around a USB accessory, at least in cases where I'm just dealing with one memory card format. (It's actually very rare these days that I have to deal with anything other than SD - though I do sometimes travel with a USB card reader just in case.) I like that even if I forget to bring a card reader with me, my 901 can read SD cards for me... Other netbooks are even more handy in this regard, as they feature multiformat readers...
I honestly wouldn't want to run a machine like this on AA's, and I'm not sure that having that capability is worth the trouble - but I do kind of like that they threw that feature in there. I can imagine a couple years down the road having trouble finding a replacement battery for my 901 (well, Asus uses the same battery pack in other models, so maybe I've got a while before that would be a problem) It's kind of nice that this machine uses "off-the-rack" li-po batteries instead of proprietary packs, and the AA fallback option is interesting... Reminds me of my old TRS-80 model 100, actually. :) I've seen tons of old laptops at flea markets - rendered not only obsolete but fairly useless as well as a result of the batteries having gone. Meanwhile, I was using my model 100 to type up reports in the late 1990s. The idea of a machine like this being genericized to the point where replacement batteries can be found anywhere is really appealing - even if the machine is very weak by today's standards.
Overall, I'd say the machine is pretty much junk. XD But it's fun junk, like the way the original EEE 7 and 9 inch models were fun junk. When they mention an internal USB slot it makes me think that they've got hobbyists in mind as much as anything... Netbook hackers just love an internal USB slot. :) ...Though it does seem that you need that slot for wi-fi, so maybe not?

You're right, batteries are a terrible idea! We should be powering our laptops with gasoline engines!
I did RTFS, and even went to their site
- $200 is a lot, there's netbooks for $250
- the datasheet lists an external SD slot, the summary says there aren't any ?
- available with up to 1 gig RAM
- optional "real" batteries instead of 8xAA
- Vista certainly not supported, otherwise they would say so.

I have a 4-cell charger that will charge 2200MaH Ni-MH cells in 15 minutes. Special cells, but damn, I can recharge a spare set in about a half hour. Not unreasonably priced back then. These were the IC3 cells. I can't find them any more, apparently Ray-O-Vac discontinued them in favor of hybrid cells, not the same thing...

Soon on Slashdot, we will not longer be discussing laptop computers because they are going to be as ubiquitous and cheap (as in 'Toys R Us' cheap) as the humble pocket calculator.
My Dad's first calculator cost $300 and it took a full pack of AA's and it had glow-y red numbers inside tiny light bulbs or vacuum tubes or something. And it came with a power cord. And it was the most exciting thing in the world! If there had been an internet back then, there would have been feverish discussion and hardware hacks and all kinds of 'boy' chatter regarding it and other devices competing for the same market.
But nobody talks about pocket calculators much these days. We've solved them. They're done. They work perfectly, and most of the time the build-quality is somewhere between "Fischer Price" and "Dollar Store G.I. Joe reject".
This is the second computer on a chip I've seen this week. ARM had an even smaller system which out-powered the one in this article by many orders of magnitude, all destined for the same market.
Yeah, it's kind of cool that portable computers are about to be Capital-S SOLVED; that we'll have long battery lives combined with high computing power in a small form-factor, all for $29.95 (or less). Great. Computers are going to be no more exciting than a new binder, pencil case and protractor set. -And probably about as durable, because stuff that lasts doesn't make money. Welcome to the Industrial Age.
Sigh.
So stop and look around. These are the last of the, "Good old days". Breathe it in, folks. It's never going to be the same again.

I am not sure about it being sealed. When outside, the adapters are sealed because there is plenty of ventilation to cool it. When inside a computer, it may not be sealed. I have opened hundreds of devices and haven't found one having sealed power AC to DC converter inside.

Recently, I received shock from my iron even though it had a ground pin (I was not ironing, so I was trying to test, if it was hot enough). When I opened it, I found that the ground wire was broken and live wire was touching the metallic case. This was just at the place where it was receiving 3 pin input. So even if the AC to DC converter is sealed, you may not be safe.
My Bluetooth-enabled Tandy Model 101 runs on four AA batteries.
Sir! Ill make a bet you will not get laid this semester! ;-)
This reminds me of the time when I was in Nuremberg and the batteries for my camera died.
I ran into some random shop and managed to get a new pack of AAs without even needing to speak the language (I speak _some_ German, but I have no clue how to say 'AA batteries')
So, say you're in some random city outside and the batteries die. Where do you plan on plugging in? Sure, a laptop is a bit different than a camera, but still. You can't plug in everywhere. You _can_ usually find batteries everywhere. What if you're taking a 12 hour flight? Sure is nice to have extra batteries to switch out in such a case (I carry a spare for my laptop in such occasions). Or if you're on a train? Or even a coffeehouse without public outlets or where the public outlets are all in use or far away.
Let's see, this week alone I've been in the following situations where I would _like_ to be able to charge my laptop but no outlet was available:
Running a table for a student organization on my campus. There are no outlets where they place the tables, and I can't exactly just move. And hell, in the summer we do those things outside.
Attending a meeting. Yes, there are outlets in the room. Two of them. No, there weren't any open chairs near the outlets.
Hosting a meeting. For some reason they didn't think to install a power outlet anywhere near the VGA input for the projector...
Just sitting outside doing work.
And this is on a college campus, where everyone has laptops with them damn near all the time. What about third world countries, which is what this laptop is really _designed_ for? You really expect children in a third world country to have access to a power outlet absolutely everywhere that they go?
Your comment sparked an interest and I just couldn't resist replying.

You have good points on trash and packing though. That's a big price people pay for a lot of things today, then it just turns to junk instantly. My non favorite is blisterpacks. I keep aviation snips handy just for dealing with those things. They *are* good packaging, but a pain to open and then how to dispose of them cleanly?
Sometimes I wish they had an area right outside the checkout lanes where you could open your purchases, and they had a recycle bin sitting there for the packaging junk. Or just have lockable generic packages with clear covers to see what is in there. You pay for the item, it gets unlocked right then after ring up, they retain the packaging and it goes to the back where the next item-whatever that item might be that could fit in it, gets placed in there, then back out to the shelf.
Actually when you think about it AA batteries do kinda suck... At least non-rechargeable ones are a bad idea. It is a nice way to needlessly fill landfills with horrible chemicals. We should probably put some sorta tax on them tbh (like shitty incandescents), people would switch to liions or rechargeables without any issues.
And yes I do realize there is some sort of rule about disposing batteries that is completely ignored in north america. My japanese prof actually asked the class one year wth we were supposed to do with them since she'd had a bag in her house filling for like 3years. Clearly it isn't effective.
Yup. Agreed. Actually this guy brought up a point I did not see myself, namely that I rarely hold anything plugged directly to the power grid against any part of my body for extended amounts of time while holding a cup of liquid over it, and perhaps it's a good thing I don't.
I'd still be using my Newton if I thought AA batteries were the best way to go.
You can get AA form li-ion batteries. The advantages are many though. AA batteries are easily replaceable being everywhere. They are a very common standard so if you want so li-ion ones you can. Since they are so common they are cheap! And available in poor countries. This is not something that is so useful for you or me.
But I think this type of design could eventually/soon get laptops under 100~150$ and that would be a very good thing for poor countries. By type of design I mean using as many common and flexible parts as humanly possible, and simplifying the design as much as possible. This allows people to repair it themselves for some parts. Replace broken parts with whatever they can find if compatibility is high (also good for upgrading). And people can more easily learn to do it. Look at poor countries and you'll see amazingly ingenious kluges. Jury-rigging whatever they have available to suit their purposes. Carts built from bits of fence, bicycle, table and an old motorcycle motor for example. Assuming this is going to continue, designing a computer that embraces it as much as possible will be successful.
Side note: I think they should have dropped the SD card completely and had another USB slot instead. This allows for greater flexibility and simplicity. Stick a drive or USB stick in there, done. Probably more common than SD cards, more or equally portable as well. As well, the screen could be plugged into a VGA plug, might add 40c~1$ to the cost but if the screen breaks people could find a monitor in a dump w/e and get it working. (Keyboard has this functionality through USB already, plus KBs rarely break.) You could probably have the thing charge through USB as well. Technically you could probably design the CPU to use a USB stick as ram but that might be a little shitty (like 1/8th the speed lol). Either way I see the power of standards being underused here.
BTW, everything I listed is the opposite of apple. So your suggestion was pretty friggen idiotic. An irremovable untouchable unmodifiable non-standard expensive ass machine is fucking retarded for this use.
That would accelerate startup times of programs. (But at the expense of RAM, if not properly done.)
One question: If the chip forces you to use Linux anyway, then why did they not use a ARM chip, and save even more energy? :/
There are so many easy-to-solve problems in this one, that it boggles the mind.
Batteries: Use a normal lid. Maybe with a locking mechanism. But not with screws.
SD: cut a opening in the case, and you have a SD slot.
WLAN: Same thing. Just make it so it has one smooth surface with the case, when the stick in inserted. And offer a way to eject it / pull it out. (A mechanical button will do.)
etc.
Any sufficiently advanced intelligence is indistinguishable from stupidity.
You don't swap them in and out all the time. TFA says the batteries can be charged in-place, so there's no need to remove them unless some kind of situation arises.
If libertarians are so opposed to effective government, why don't they all move to Somalia?
Suspend/resume is hard to get right. It didn't work on the XO for quite a while, and then when it finally was a supported feature it could trash the external SD card. (That bug was squashed several months later, wasn't it?) There are potential problems with devices on USB (like the wifi in in this EduBook). I think the XO-1.5 redesign included several changes for the purpose of better enabling suspend/resume. (And the XO also had the audacious goal of supporting micro-naps with near-instant resume to really extend battery life, which unfortunately they never achieved.)
Really, having no suspend/resume is just a total dealbreaker for a laptop that isn't chained to the classroom wall. Plus it's an indication of a not-well-tested product IMHO.
Ah, you're that person companies have to write stupid shit like: "Don't get in the bath with this laptop", for indemnity, and because you're retarded.
So this cute little laptop was taking a bath, and I wandered by and thought "Damn! I'd like to get into the bath with that laptop". So I undressed and hopped in and .... KAPOW! Electric shock!
Doesn't anyone else think that when they see "Don't get in the bath with this laptop"? Someone? Anyone at all?
I am anarch of all I survey.
It doesn't use Alkaline batteries, only NImH rechargeables or a LIon battery pack. So, you won't be replacing batteries for $1.79 a set. But a $13 set of AA Rechargeables (bought in bulk) is a lot cheaper than a $50 - $100 proprietary battery pack, and a available easily from multiple sources.
You can also use a 2.5" Laptop HDD or an SSD in the same form factor or interface. As far as I have been able to find out, there is a lot of flexibility in options.

Even among pocket calculators there's a huge variety of different devices. Some are for complex scientific work, others are just for adding up your weekly grocery expenses. Surely the complex scientific calcs are going to continue to evolve, just like laptop computers will continue to evolve. Either that or they'll be replaced by all-in-one devices like smartphones running specialised software.
I agree with the gist of your post, I think we'll see more and more "appliance" type computers which will be so simple to use that they'll be like everyday appliances which anyone can use intuitively. At the same time we'll definitely continue to see "real computers" which are customisable and hackable, though the market for these will no doubt be smaller, since most consumers just want something which works out of the box.
Rest assured there'll always be something geeky for people to play around with.

Well, Since NImH AAA batteries run at the same output as Alkaline AAA batteries, there is nothing to say you could NOT run them on Duracells.
You just can't plug the thing in with the Alkalines installed.

There is, arguably, one major exception: Low drain devices.
For high drain devices, the life of the battery will be overwhelmingly shorter than the life of the device. A computer that might get 4 hours on a charge might easily last 4 years. Primary cells would be an extraordinary waste, rechargables are the only way to go.
For a low drain device, like a little slice of battery backed RAM, battery self-discharge could easily exceed load drain. This means that a modestly sized lithium primary cell will last a decade, no big deal. You are still an asshole if you make it completely impossible to replace such a battery(Solid block of epoxy or the llike); but requiring basic hand tools, or soldering, once a decade isn't exactly a huge burden. Particularly if it is for a device that usually has a 5 year lifespan.
It's not recommended to use Alkaline batteries. You're welcome to try... It wouldn't take long at $5 a set of 8 to exceed the cost of the unit. For $13 in bulk, one would have a set of batteries that could be reused for a long while.
Indeed, some people don't like them, but there's much less resistance when you tell them in parallel.

Perhaps you could use the external SD socket as, well, an external SD socket.

Same power got me flowing. Say, we're done a full circle with these now, aren't we?
Likewise, do you really expect children in a third world country to be able to run down to the 7-11 and pick up 8 new AA batteries? Remember that whole "$0.50 feeds this child for a week". Hmmm, batteries for my laptop for a few hours, or food for the next three weeks. That becomes a pretty tough decision, where batteries won't win.
I will agree with you, it's been nice to be able to swap batteries in my camera on demand. But then again, I've been in civilized parts of the world when I wanted new batteries. It doesn't take going to a starving country to find batteries difficult to acquire. On a few cross country road trips, we didn't bring enough AA batteries, and stopped at tiny gas stations in the middle of nowhere. Like areas where it's 100 miles between exits with anything resembling civilization, and even that is just a gas station with an old generator powering it, because there's no way the power company will run 100 miles of wire for one store.
Usually you do ok with the shelf life of batteries in most stores. There are places that may sell a set of batteries every decade. Sometimes we'd get the batteries, and be on our way before we put them in the camera, just to find out that they were well beyond their shelf life.
That's in the luxurious United States of America, where we have paved roads almost everywhere, and you won't find entire cities of people starving. Ya, I don't expect they can just buy more batteries when they want. But, batteries may be more accessible than power outlets.
Serious? Seriousness is well above my pay grade.
I wonder if you could add one more battery and be able to then swap out all of the batteries one at a time without losing power.
Just because you're well educated doesn't mean you can't be an idiot. I've know plenty of smart people that are completely stupid.
Regardless... I am in love.
Seriously.

Hi,
I liked that review. It was interesting enough for me to read it in full, and you seems to have covered everything I wanted to know, with no uncalled for overhyping or bashing.
One minor gripe I have, not necessarily with your review per se but in general:
Sure, GNOME and OpenOffice.org take a long time to start up, and Flash runs like molasses unless you have a beast of a CPU, but let's not hold that against the devices. It's the software that makes it that way. Every time a low-power device is introduced, people note that it doesn't run $heavy_software_of_choice speedily. Well, of course not. That software was developed so that it runs passably on the fastest generation of desktop hardware.
Imagine not, what the experience could be like running heavy software on faster hardware. Imagine what the experience could be like running lighter software on the same hardware.
Please correct me if I got my facts wrong.

This is hardly revolutionary technology the Sony MZ R700 MiniDisc walkman came with a rechargable battery and a charging circuit so you can charge it from the wall wart. The best part is that its an AA battery, so not only can you swap it out for a standard AA in a pinch you can also stick any other rechargable AA in and use that/recharge it internally. And that came out in 2001 and is the tiniest most amazing piece of electronics i've ever laid hands on, I bought a "new" one off ebay just a couple of weeks ago.

Michael Barnes' company, NohrTec, is about 3km from my Bangkok condo, and I appreciate what he tries to do. All of his products are very FOSS-friendly. He even had a special version of Puppy Linux for his old MicroClients (I own one, and it runs Ubuntu 9.10 perfectly). There aren't that many companies out there designing hardware specifically for Linux and low-poer requirements, and he probably deserves more exposure than he gets. He certainly deserves as much as Pandora and the like get.

AA is a form factor. It is a popular form factor for rechargeable NiMH batteries.
Reading between the lines, this device has a battery pack made out of rechargeable AA batteries, which it recharges when it is plugged into AC. Just like a laptop really, except instead of an expensive Li ion battery it uses something cheaper like NiMH, and in a pinch you can throw any old AAs in, although you'll need a screwdriver to extract the "battery pack".

Actually, the old TRS-80 Model 100 from the early 80's ran on AA batteries. There was some merit to being able to run down to the corner store when you were in a bind. Yes, I used to use one of these. It was a damn cool computer at the time.
Low self discharge NiMh cells are supposed to keep 80% of their charge for a whole year. They're also more robust cells than the higher capacity NiMh cells, so they'll keep their capacity longer and provide a better band for your buck in the long run.

They're using NiMh cells with 1.2v nominal voltage.
8 * 1.2v = 9.6v

Soon on Slashdot, we will not longer be discussing laptop computers because they are going to be as ubiquitous and cheap (as in 'Toys R Us' cheap) as the humble pocket calculator.
Intel and Microsoft disagree with you on that. They're doing everything they can to keep regular laptops costing around $500. Both companies have restrictions on the hardware that can be put into a netbook. Manufacturers who don't follow the rules miss out of preferential pricing deals which essentially prices them out of the market.
The only real hope for $100 netbooks is ARM + Linux. You can bet your life that Intel and Microsoft will do everything possible to derail the ARM train.

And the other side of the argument should also make note of 3D videos and increasingly realistic games which will no doubt require further development of chips and video hardware. I imagine that computers will continue to evolve and draw excited Wows from the audience of tech geeks.
But we are still definitely on the cusp of a vast plateau. Laptops as we currently know them are about to become something very different. Laptop guts from 5 years ago looked very much like those of today. That's about to change dramatically, and that change will have an unpredictable ripple effect.
