It's NOT a touchSCREEN - it's a touchPAD, similar to that on a laptop. Anyways, a simple function could be swiping across the pad left or right to scroll through some usable items. Sounds pretty practical to me when the controller is limited on hotkeys.
I've already decided not to get a next gen console and build a Steambox instead. I'm really hoping the Steamboxes revive couch co-op for PC games. Better controller support would be nice too.
