Honestly, I think I'd just get annoyed with the Wii U. It's the same as having those gaming keyboards that show things from the game on an screen on the keyboard: Why would I want to look downwards, away from the other screen, especially if I need to do something in the heat of a moment? If something is chasing me and I need to switch weapons, I don't want to have to look down at my controller, I want to be able to do it in stride.
Or if I'm traveling and want to look at my map, I don't want to have to look down at the map every 20 seconds, I want it in my line of sight for easy glancing.
