Yes, there are many little COTS SBCs that run linux. However, they don't give the mix of capabilities that the Raspberry Pi does for the price that it sells at.
It's always been the case that someone could have lost their phone/pager, or had it stolen. Sure, in most cases the phone will be in the hands of the owner, but it's certainly not guaranteed.
With a pager it's pretty obvious, there is no security, your phone number just displays on the screen. So I think they're correct there. Similarly, with many dump phones an incoming text message just pops up on the screen.
Now in the case of a smartphone with a password then in my opinion you could reasonably argue that you would have a reasonable expectation of privacy sending information to it...but technically speaking I have no way of knowing what sort of phone the recipient is using when I send them a text. They could have broken their smartphone and temporarily gotten a dumb phone as a replacement.
Fundamentally nobody is willing to do what it takes to deal with carbon emissions...it's perceived as too expensive.
On the other hand, geoengineering solutions (if they work) would be cheap. I heard an estimate that a fleet of small autonomous ships spraying seawater into the air (to seed clouds and increase albedo) would cost ~6 billion. That's nothing in comparison....there are individuals that could afford that.
Count me as one of the few then....when writing anything remotely substantial in Word/OpenOffice I always use autonumbering, styles, headers, etc. So much simpler to define the style once and be able to change one thing and affect the whole document.
Do you move house often enough that keeping toe packaging to help moving actually makes a difference?
I once moved six times in four years. At that point it *absolutely* paid off to keep the packaging around. Now that I've bought a house the packaging for almost everything has been chucked.
I think it would be entirely reasonable to have a time constraint such that the information can be kept private for a strictly limited time for exactly those reasons. But in a case like that the statute of limitations (or equivalent) should apply only once the information is made public.
On surfaces like gravel and snow (both of which exist in plenty around where I live) ABS actually gives longer stopping distances compared to locked-wheel skids. On the other hand, it does let you continue to steer while braking.
As far as I'm concerned, an unpassworded computer set out for public display is fair game for anything if there are no "please don't install software" signs. I've downloaded and installed apps on demo tablets, this is fundamentally equivalent.
The proper technical solution for the store is to have all devices periodically sync with a known-good disk image via the network such that any illicit software will be wiped.
The computers are out on display for people to use. They're not "private" computers, so if they don't want you installing software on them they should say so. (Or more likely if it was me I'd have them all periodically re-sync to a known-good disk image over the network.)
If they didn't want people installing stuff on them, they should have locked them down or scrubbed them periodically. Heck, I've downloaded and installed stuff on demo tablets which is essentially the same thing.
I think Apple makes awesome hardware, but it's more expensive than I want to pay and the lower-end ones don't have nearly enough screen resolution.
I'd be perfectly happy with a less-expensive i5-based 15" chunky ugly laptop with a crapload of memory and a super high res display. But nobody makes something like that--only the ultra-high-end stuff gets the high res display.
The whole point of a computer is that they're general-purpose machines. There's a lot of flexibility, which creates a lot of complexity.
A single-purpose computer is basically a kiosk...someone has programmed it to do one thing.
Modern TVs are basically kiosks...under the hood they run linux, but they're generally limited to media consumption. However they're much more complex than they used to be, with built-in netflix, youtube, HDMI-CEC, ethernet connectivity, etc.
Most tablets/smartphones are a bit further along on the complexity curve...more complicated than a single-purpose device, but less complicated than a full-blown computer.
Ultimately you decide what you want the device to do, then pick the device that fits your needs.
While it may work for some things, it's certainly a non-starter for me.
A tablet has nowhere near enough resolvable screen real estate to compete with someone using a decent desktop monitor, much less a dual or triple monitor setup.
Doing any sort of serious development on a tablet pretty much assumes you've got a backend server somewhere doing the compiling, whereas my 4-core laptop with 8GB of RAM is actually a pretty reasonable compile box when I'm away from an internet connection.
Lastly, tablets don't have the connectivity. In particular wifi (even at 5GHz) doesn't compare well against gigabit ethernet and eSATA.
But they had a cap so that if you took more than 6 classes per semester the extra ones were free. One year I took 7 classes first semester and 8 second semester....that was a tough year.
In a "properly" secure system the hypervisor would be signed with a key as well and the OS wouldn't allow it to boot if it's been tampered with. That hypervisor would then virtualize secure boot and only boot signed binaries, same as the real hardware.
I'm not sure why they would need a revocation list. There is a handful of keys and they won't ever be revoked.
If any of the root private keys ever got leaked they would need to revoke it, otherwise it could be used to sign arbitrary malware and bypass the whole purpose of secure boot.
Also, the aspect ratio is slightly wrong (iPhone is longer relative to width), and the back and sides are white.
Sure, it has more resemblance to an iPhone than strictly necessary (the new Galaxy 3 looks different), but at the skinny bezel, edge-to-edge screen, and rounded corners are all natural endpoints in the development of a handheld touchscreen device. Look at the Motorola Motoluxe.
Check out the other threads pointing out an issue with futexes. There's an easy workaround, just manually set the time on your system and the problem will go away until the next leap second.

Compared to gigE, it takes a LONG time to back up dozens of gigs of data via wifi. Even at 5GHz with wide channels and line-of-sight.

Although I did have a mac where you had to hold down a key while booting to boot from CD.

Saab made really safe cars, but the company was run like crap. There are good reasons why they failed.
That said, the upside-down drop test on Top Gear was pretty impressive.

If the telecom customer pays for it then people who don't do business with 4G providers won't pay for it.

30+ small children in a class is too many for effective learning
I would love a phone with a touchscreen but on which I can also feel the buttons. Haptics, dynamic morphing, whatever, I don't care how they do it.
Did they license it, or is there more to this story?
But they had a cap so that if you took more than 6 classes per semester the extra ones were free. One year I took 7 classes first semester and 8 second semester....that was a tough year.
