Creating the World's Cheapest Tablet
Back in October, we discussed news that India had launched a $35 tablet. Now, JohnWiney writes with a story in the Globe and Mail about the device's development. Quoting:
"Part of the difficulty in engineering such a device is that the underlying goal—that its final price should be within the means of those who can’t afford high-priced tablets—dictates crucial engineering and component decisions. A piece of high-impact-resistant glass, such as the touchscreen face of an iPad, can cost upward of $20. Datawind’s touchscreen glass, which the company had engineered down the street, costs less than $2, though it won’t allow for luxuries like pinch-and-zoom finger swiping. There were also compromises on processing power: Datawind’s 366 megahertz processor costs less than $5, a fraction of the $15-plus price tag on the chips that power iPads and other comparable tablets. And while the decision to run Google’s free Android mobile operating system on the gadget saves money, it requires coders to dig deep into the Linux kernel that underpins the software, tweaking it until it runs smoothly on Datawind’s weaker processor."
You're posting this on a forum where a good number of readers are obsessed with Linux. It's not that Linux isn't a great OS (I use it for server-side stuff) but it certainly doesn't provide the polished overall experiences that Microsoft or Apple do.
There is a breakeven point for many people. Those people who are happy to pay $200 for a machine and spend the time getting it to run well with something like Linux even at the expense of a better experience which may cost 6x as much (Apple).
So, if someone cannot or is unwilling to pay $500 for an iPad but may be willing to pay less than $100, it's going to give a much better experience than nothing.
Ha. You old people are so funny. You could never do anything real on a 366 MHz processor. I mean, like, the Android I got for christmas has at LEAST 1200 megahertzes. I bet they had at least that when they went to that moon or invented the awesome SR-71.
Who are these indian kids that would even get this. I would be soooo mad if someone got me this for christmas. Such a horrible gift. No one could ever even use it.
Let them have the original iPhone.
It doesn't seem worth it for the compromises made
So if you're an Indian for whom an iPad costs the equivalent of a year's salary you should go without altogether, rather than have the best-in-breed? Sounds like a plan - Since I can't afford a Porsche I'll stick with walking.
Depends a great deal on the distro. I've been using Linux Mint and I've spent very little time trying to fix it, probably similar to how much time I've spent trying to fix Win 7.
OTOH, Arch, Gentoo and similar are aimed at people that are more interested in controlling their complete experience, and probably take more time to maintain.
Lord knows I have a million and one uses for cheap tablets. I could stick them to the back of the seats in the car, to shut up the kids in a long road trip. Stick one to my dashboard and connect it to a bluetooth ODB-II dongle. I would stick one to the front of the fridge to turn it into a new smart fridge. Hell, duct tape them to anything to smarten it up.
It would also make a hella good universal remote for the lounge.
Problem is now that tablets are spiffy high price gadgets with premium hardware and spiffy graphics that cost the same as a entry level laptop. I'd have one tablet to do all those things and have to carry it with me. Things will change radically when tablets really do become as cheap as they should be. Cheap enough and we'll start covering surfaces with them.
All the interface animations and physical metaphor graphics (brushed metal, wood grain - Apple's microsoft bob era design philosophy), but after a while it's no benefit and a small waste of your time and battery power every time you watch a 500ms transition animation. They just get in the way and in the end I'd rather have more battery life/response/cheaper hardware.
I really cannot wait to get my hands on a useful $99 or less tablet that actually doesn't look good, is rugged and doesn't have fancy graphics.
After logging in slashdot still does not take you back to the page you were on. It's been that way for 20 years.

Major flamewar imminent! EVERYONE, GET TO THE BUNKER!
Currently there are ARM Cortex A8 tablets with 7" LCD's using the $5.00 Allwinner A10 ARM soc on sale for ~120ea.

The actual cost to build them is around $60 ea

> You're assuming that any device is necessarily better than no device.
Um, no. He's assuming that the Datawind tablet is better than not being able to use the applications the tablet provides. I know this is hard to understand, but if you need to run an application to help you plant your crops, a device that doesn't happen to have a trendy metal bezel and won't play Angry Birds is still better than not planting your crops.
It's not about the device, it's about access to content.

For people with NO alternative experience, even weak devices can change their lives.
Would you rather have NO computer, or a Celeron 500 with 256MB RAM? Those specs don't even merit a dumpster dive nowadays in the US, but don't forget what you can do with one.
"This post is an artistic work of fiction and falsehood. Only a fool would take anything posted here as fact."
Then... I have an idea -- why don't you go tell them that. Someone over there thinks there is a critical need for a device at that price point. It's easy for us first world residents to say they should be buying iPads instead without any appreciation at all for what life is like in that part of the world. The last time I was there, the houseboy slept on the floor in the hallway outside my hotel door, because it was more comfortable than his home. (I asked him.) Away from the cities, the great majority don't have access to any of the things you take for granted -- GPS, cell service, access to the internet. It's a totally different environment. *We* think you're a little nuts for camping outside the AT&T store in the rain waiting to replace your 4 with a 4s. People in *that* part of the world think you're batshit crazy.

I don't think you realize how much more productive the farmers in the US became after they were able to get their hands on the bulletins and advisory pamphlets that the Department of Agriculture put (and still puts) out. Or how much science goes into running a farm. How much information is required for successful farming.
Apparently, you're not familiar with the business of farming and how much of it depends on an up-to-the-minute awareness of market conditions, weather conditions. economic conditions, and forecasts. Even their bank balance.
Having access to a bit of technology that allows them access to a library of information and online data could definitely mean the difference between a farmer making it or failing utterly.
Why don't you let the farmers decide whether or not they need the trendy metal bezel and SIRI or not?
And yes, any device that allows farmers to ask farmers all over the country "how to do it" is better than having them asking only the local farmers. They could get information about pest control, get help with crop diseases and learn about various types of fertilizers. Indeed, the communications capabilities of a basic tablet could help them ask the local farmers and maybe participate in discussions with ALL the local farmers.
I guess you think they all just drive their tractors or mules and meet up down by the barn with hayseeds 'twixt their teeth to tell each other how to plant a potato.
I don't care if they're sustenance farmers in rural India or a Wisconsin dairy farmer with a few thousand heads. They're using tons of data and having access to that data in the form of a handheld tablet could be a real boon for them. Farmers here in the US are probably among the small businesses that make the greatest use of the Internet and personal computing technology. For some of those farmers, the Internet is a literal lifeline.
You are welcome on my lawn.
it certainly doesn't provide the polished overall experiences that Microsoft or Apple do.
Nice switch. The Linux variant being discussed by the OP was Android, which is by all accounts pretty polished (the latest version in particular has been widely praised), but your then go on to define your argument against Android based on desktop Linux distributions. Desktop Linux and Android are not the same, so this line of reasoning is completely invalid. I could go on and point out that many people don't care about visual bling, and how it's taken years for Windows and OS X to incorporate support for simple concepts like software repositories that Linux distributions have had for over a decade (do the Windows and Mac app store repositories even do dependency tracking across packages yet?) Linux isn't even a desktop. If you're going to say that something isn't polished, at least tell people what you are talking about - Gnome, KDE, Xfce?
Well by putting their system reqs at frankly ludicrously low levels what you ended up with is OEMs slapping Linux on machines that frankly would have had trouble running Win98 without hanging and gave Linux a worse view from those that don't know about specs and just look at price. i mean a 366Mhz CPU?
To be fair, I have a 400 Mhz P3 that has performed admirably for a decade or so with effectively zero downtime as a dev server and network monitor for a production server cluster. To say that you can't get significant use from such comparatively scant resources is simply wrong. I manage my expectations... I am not expecting a responsive, HD flash video experience, nor am I expecting to render expressive graphics with a "snappy" experience.
Look at this as a research project: how do you get a good experience at a reduced power level? You aren't going to get a good experience at 366 Mhz, but given just two Moore's law doublings, you are up to 1.5 GHz, roughly in line with today's midline tablet processors. That's just 4 to 6 years away, depending on how you interpret Moore's law.
The lessons learned today will result in a much better experience for future users of both "low end" and more mainstream processors.
I have no problem with your religion until you decide it's reason to deprive others of the truth.
