This is a neat idea and clever execution, but I just can't imagine ever using this over like a donated out-of-date laptop or something. I'd love to see something at like a 50-100 price point that could theoretically be more usable (more than 47 keys, more screen resolution, built in wifi)
I've sometimes thought about going to some small village somewhere and teaching interested locals how to code and use computers. I would need small, cheap devices that I can just replace whenever they get lost/stolen. Also standardized enough that I don't have to spend a ton of time doing hardware support. If someone brought a >$20 fully-contained device to market then I could buy 20 of them and plan a 6 month trip abroad. Being not super-useful as general purpose machines is a bonus.
This idea's been kicking around in my head since the OLPC was announced, but nobody's delivered yet. Chromebooks are too expensive.
It would be nice to have. One thought I can't shake is how wasteful the world is with perfectly good hardware that's "obsolete". For instance, I have an iPhone 5C that I practically can't give away which is way more powerful than the idea presented here. But because the hardware is undocumented and locked down and it's stupid difficult to replace the battery, there doesn't seem to be a reasonable way to turn it into a cheap computer, even though it really should be possible. (To be honest, I'd probably still use it as my phone if it still received security updates and I could replace the battery)
