Here is a quote from Bill Gates' about the Wii's controller:
Sounds like he's a little upset his next-gen system is the only without motion sensors.
Bill Gates said:There's room for innovation here, but moving that controller around -- it's something that's not mainstream for most games. It's tough because sometimes you move the controller, and you don't [mean] to fly into the ground. You just want to put the controller down. People aren't that good at totally standing still. Even pilots actually sit in a chair when they do their flying. So there's a lot to be learned about these controllers.
