Bill Gates has weighed in on the Playstation 3 motion sensing controller debate saying that it is "not mainstream for most games." Speaking in an interview with MTV News, Gates said that while there is room for development in this area, "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."
