This is cool, but I'm mostly sad the future of computing is so closed. I can already see that you're not going to be allowed to do a lot of things on these devices to the point that they're useless, like iPhones.
You seemingly have to do everything yourself, which begs the question why not just go full blown Linux distribution, and throw on some sort of Android app emulation?
I'm in the midst of debating moving us to just Linux or sticking with Android, and the list of things to replace isn't insignificant.
