It all depends on your application off course, but I'm going to be dare-devil and claim that the GUI is at most half the program.
So, even though you may need to convert the GUI from 'PC' to 'Tablet'; if things are decently written you can still re-use quite a bit of the underlying code/layers and it all is handled nicely in the same dev. environment you're already used to. I do think it has a lot of things going for it.

I've had goods delivered worth hundreds and not even have to sign off for it. (not that those scribbles are worth much IMHO, I've never understood why they don't require a picture of the person accepting the goods... heck, have them hold the package with the label clearly visible, should make denial-ability (sp?) much more cumbersome than it is now)
I've also had goods delivered worth peanuts that required showing my ID and the person in charge copying the number on some form and then me having to sign it.

Courier services are weird at that sometimes... I'm guessing it has to do with the type of insurance that comes with the company/package/...

Weird this got modded 'Interesting'.

Sure, we pay people to have those goods delivered to our door; it's called a service and the people providing it need to feed their families too. That said, if you eliminate those costs by 'automating delivery by way of drones', you'll add the price for buying/training/maintaining these and the whole infrastructure that comes with it; hence, you eliminate known costs by adding new guesstimated (bigger?) costs. TCO is mostly a buzzword in my vocabulary, but in this case it probably is worth having a look at. On top of that you'll probably need to keep a backup 'manual service' at hand anyway because these things won't be able to do their job when it rains/snows/storms/... heck, a bit of wind and you're finished. Nobody cares if the postman wears shorts or a scarf, we 'know' he'll come through.

Also, you may consider bicycle couriers a nuisance, having these things whizz around everywhere sounds (!) much more annoying to me. Might look 'cool' in Sci-Fi movies, it would get on my nerves quite fast in reality I think.

The part I'm I think will be the big show-stopper is the likelihood of people 'catching goodies from the sky'. Given the technical restrictions of these drones it seems fair to assume they'll be used mostly for 'small but expensive' goods. What's to stop people from building a microwave-gun to fry the electronics and run of with the cargo ? Heck, a decent slingshot could probably bring them down. I realize one could rob any courier service, but with drones it's going to be dead-simple unless they start building in all kinds of security measures but thus limiting the capacity/range/... of the machine.

Experience shows differently : SSD works perfect day 1, isn't SEEN any more by the BIOS the day after. Tried on different machines afterwards. And no, nothing special happened to the laptop in the time between. Simply went to the hotel and back to the client the day after.
(And no, it wasn't an OCZ but for the love of god don't remember if it was a Samsung or Crucial)

I've never had that happen to a HDD. That doesn't mean I've never had spinning platters fail on me; but usually things there start by either
* SMART reporting non-recoverable errors
* major slow-down of the entire system for no apparent good reason, usually accompanied by a HDD-LED that simply simply keeps on all the time.
In all cases I was able to recover 99% of the data on there. In one case I had to put the disk in the freezer (USB enclosure) as it would only work when the temperature was _very_ low. Sure it always took a long time to do and was a PITA, but I still prefer that to the failing SSD.

I've heard the theory over and over again that an SSD that runs out of writes will settle as a read-only disk so you might not be able to run an OS from it any more, but surely can mount it as a data-drive to recover all your info.... In practice all I've heard/read/experienced is that things look A-OK for one moment and go poof the next.

Don't get me wrong, I love my Samsung EVO and I've revived my dad's pc with my old Intel SSD; but making sure to backup things on a regular basis is absolutely crucial.

I didn't research so forgive my ignorance, but if they might be able to produce this cheaply and durably; having a couple of m2 of it on your roof might be great for capturing solar energy; especially given it's heat conducting properties. It would look weird though.

That said, didn't we have a similar article on /. quite a while ago where they showed off something similar (might have been it reflected (quite) a bit more) yet I haven't read/heard anything from it after that...

My neighbour has a laptop like that and it's a PITA.
I'm not sure what exactly I should blame, the hardware implementation (via the BIOS) or the OS (W8 so I'm sure half of /. will jump on it, don't bother) but it seems that the 32-ish (?) Gb of mSata is being used as some kind of cache for the BIOS that tries to buffer (read + write) towards the HDD. I've been considering putting linux on it simply to see whether this would benefit from this too (meaning it's pure BIOS, which going by the error-screens I think it is) or not (meaning the OS needs to play along somehow).

In theory this should work great, and yes the machine is pretty fast I/O wise, but in practice it really sucks when things go south and somehow fails to properly write everything to flash and then when you boot again the entire file-system is corrupted beyond repair. This happened twice in a 2-year span already and the only solution seems to be re-imaging everything from the rescue-partition thus losing everything that was on the machine. As a result they now save everything (photos etc) on an external disk rather than on the internal disk.

I tried to teach them how to create an image-backup with Redo-Backup but it seems the machine simply isn't capable of booting from anything different than the (cached) HDD ... I also tried to see if I could allocate the mSata as a disk to hold just the OS and some programs instead of being used as cache, but again found no such option...

Hear, hear. I have a passively cooled DN2800MT in the living room for my kids to play with. It's sufficiently powerful for most online games (think candy-crush) or GCompris or oldish (so called educational) games they find at the library (**). The only moving parts in there are the DVD and HDD. As expected, the DVD-player is 'loud' but although the hard-disk is a modern and fairly silent one; you absolutely notice it whenever the OS puts it to sleep!

(**: Most of these cd-roms come with minimum requirements along the lines of 'Pentium 166 with 4Mb of ram'. Not that I mind, but when you come to think of it, it seems that this whole industry peaked around 10 years ago and then simply vanished ?!)

I have a D-Link router with DD-WRT running at a 'remote' location with rather 'sensitive' electricity. Whenever there is a thunderstorm I have a 10% chance that the electricity went down. As I got tired to drive up and down whenever we have bad weather in order to check if things are still up (freezer etc) I added a little cron job that simply WGETs a specific URL on one of the websites I manage. Said page logs the last 10 entries and thus whenever I think about it I can simply pull up the log and see if the router is still up. I wouldn't call it secure (anyone could spoof the call to the page if they found out about it), but for its purpose it's more than adequate.

Your code should be more efficient!
