That's very impressive on a technical level, although I'm not sure that I agree with the title in regards to the "future of computing." Whilst I am personally in favour of rugged tech that can take a beating, I think a majority prefer looks. On top of that, the idea of everybody carrying around a fully-functioning credit card-sized computer is perhaps out of touch in comparison with cloud computing. This sort of thing will no doubt have a place but perhaps not in the day to day world.
You are absolutely right, the title was a bit sensationalized. This computer is perfect for embedded computing, or servers because of its tiny size. The vision is that you would be able to build shells around it (laptops, tablets). That way if the shell breaks you can just pull this out and put it in a new shell.
