My favorite thing about this gaming concept device is that it is a hinged flat screen, kind of like a two-sided tablet. That seems to me the future of the portable UI…since you could turn it sideways and read it like a book, or lay it flat and type on it like a laptop.
Privacy is not needed on a gaming device for most things so why not add in a micro-projector? That would address most complaints about the screen size yet leave it highly portable.
