Even if I am slightly intrigued by the capabilities of that thing, it's a hideous design. The original DS looks like a work of art compared to that fugly thing.
Anyways, Alex is right. It isn't a handheld gaming system. It's a mini-PC that can play games, and I can't imagine that it'd play them well either. From the looks of things it doesn't have a decent control pad
Ditto to what Rach said, too. Something like that isn't gonna come cheap.
