Looks nice, and is certainly a nice idea, but I have this feeling that a computer that is not mobile (it needs a screen and keyboard and power and stuff) should run a decent operating system (windows, linux, osx, ...) and not some smaller 'mobile' operating system (android, ios, ...). The added cost in usuability (as in, you need peripherals) and mobility (not to say price) should be offset with performance and flexibility. (as in a decent desktop with a decent operating system).
