I mean... even if people aren't going to take it out of the house, and don't plan to ever undock it...
As a Wiiu owner I think they are in for a pleasant surprise. Being able to keep my game going when I need to go to another room, or laying in bed, or when my girl "needs" to watch something on the TV, has been so awesome.
Yeah, it really was a game changer for me. I brought my Wii U to my parent's house during Christmas holidays. My parents could watch TV while I played Earthbound. Was great.
