There’s a video up on YouTube right now, and while it’s probably completely fake, it pretends to be a possible product coming from Microsoft. The concept is interesting, but not really feasible (or at least not affordable).
The video comes from a California based design company, 13 Tech Design. As far as I can tell, they really don’t have any actual products, just renderings of possible products. Whatever the posibilities are of this being a real product, it’s an interesting concept using Microsoft Surface.
