That pocket thing looks kind of cute. Light-years outside of my price range for anything (let alone my little tinkerin' budget) -- but cute. I hadn't heard about that one before... I like it, even if I can't afford it... (silly me, I like tiny computers of basically all sorts)
Shameless (and long-winded, sorry) plug...
I'm developing a mostly-open-source (not libre, sorry) laptop called the AnyTop. ("Mostly" because it runs Windows, because I /really/ don't want to have to tutor people in Linux with this thing... sorry, everybody, but the vast majority of this world runs on The Redmond Monstrosity. It just does.) The idea is that anyone in the world who isn't blind and can use a knife can follow the instructions and build their own laptop from said instructions. The only tool you need is a smallish, non-serrated sharp blade of some sort.
For the record, I'm not planning on distributing anything /other/ than instructions, and (a) printing them requires color capability on the printer side and (b) the requirement of being language independent means that those instructions wind up looking a bit like something you'd see on the back of a cereal box, and for most "first world" people they're likely to be a bit inscrutable at first glance. Numbers are represented as hands with fingers held up, for example, and sizes are expressed in common objects and parts thereof (such as a sheet of paper or a CD), rather than customary units (inches, cm, etc)...
Full disclosure: there's this blog called Hackaday ("hack" as in "hacking together a fix" not as in "l0lzerz I'm hacking your comp00ter box") that has a 'projects' sub-site and a yearly contest for grand ideas and the like -- I have entered the AnyTop in that contest, and am keeping a log on the 'projects' side of the place as part of that -- although I don't expect to win... I rarely win anything, pretty much period, and especially not contests...

If there's meaningful interest here, and if Luke says it's on-topic (or at least mostly so), I'll link to the instructions, once they're done, in a post on this list. I'm also willing to mail a copy to anyone who wants one, although international mail will be First-Class (not tracked, no delivery guarantee, and slow as heck) unless the recipient wants to pay for it, and in all cases I can only mail to places the US Gov't will allow me to...
