To be fair, we can all see the way this is going, in a few years we will have Kinect control for everything, so you don't want to have touch screen for your HTPC? Duh obvious, but you can sit on your couch and wave a hand in the air and it will run programs, play videos & music, etc - so to give a Metro style UI for Xbox is halfway there already.
No more game controllers or remote controls to lose, no more batteries running out, no more having to get off my fat lazy ass to pick up a controller or remote I have put down more than 3 feet away. Heaven for couch potatoes.
