actually yea, if they would have left the tablet controller out, and hell, made it work with the Wii-Mote and the classic controller and literally been just a Wii HD, I'd be more on board than with what they are doing now.
I see a lot of useful things that could be done with the controller, but I can also see it becoming easily like it is with the Wii now. Nintendo's games will utilise the screen in neat, innovative ways, and larger third party devs will utilise the screen in broken ways, or ignore it completely. Much like we see now with the Wii's controls.
