I was talking to one of my friends and he said he was going to get a PS3, I asked what games he'd get with it and he didn't know. I asked what he thought about the controller and he said 'what about it?' - didn't know about the tilt sensors. I asked him why he was willing to pay so much for one, he didn't know that either.
Doesn't really prove anything though, you can get people just as mindlessly buying Nintendo products...
