The Steam box streams, in a sense, from your PC to your Television. This is nice and all, but I don't have a PC. Or a computer, for that matter. But there are lots of games on Steam that I want to play. The Steam box should be a stand alone console. You should be able to plug it in to your TV, then make a Steam account with a good UI, and buy and play games. Of course you can have your pre-existing Steam account and transfer all your games and such. The controller should also just be a standard 360 style controller.
