Breaking news! Bill Gates doesn't think the controller is so great.
Problem with his comment on the Sidewinder is, THIS is why Nintendo is in the hardware business. It can push a new concept to the public in such a way that the only way to ignore it is to not consider Nintendo at all. With the Sidewinder, it's just another faceless PC accessory that probably only worked with a few Microsoft games. With the remote, if you own a Wii, you
will use it.
As for comments on moving around and stuff, may turn out to be true, only time will tell. Sounds like excuses to me.
