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)
