No, it's not a $100 Android box - it's a 100$ Android console. And I don't know any other Android system specifically designed for that so far. You don't keep your mobile phone or tablet plugged in to your TV and neither do you plug in a game controller into either of them usually. Also generally tablets do not mainly care about improving performance specifically for games, which mean given the choice of faster 3D or improving other hardware parts a typical tablet will not go for 3D. And yes - easy porting games to/from other Android systems is one the big selling points. If you think a computer is a computer then there is pretty much no point for ever buying a game console, nearly everyone has a more powerful PC in the house already.
