From my experience, I would rather keep my old Wii setup and use it if I have a desire to play an older game or any of those Virtual Console games. The Wii U as it currently exists is slow to navigate and cumbersome, Wii functionality feels like a crammed in afterthought and not a fully integrated backwards compatibility. I would have rather they didn't bother with it if this is the best they could do. Don't get me wrong, I'm enjoying the system so far but to go through the multiple steps and loads required to play a Wii game is just not worth it to me. The Wii is pretty small the solution for me is that it gets to live alongside it's new brother for a while longer.
