I got one for Christmas. I wouldn't have bought it for myself. But I have to say, I'm having a lot of fun with it. A friend of mine came over, made some apple martinis, got drunk, ate Thai food and played Kinect Adventures for a couple hours. She couldn't stop laughing, and I had a good old time. And we are both in our 30s. And the public awareness is out there. I asked NO one for it for Xmas and I received one from all three people who would possibly buy me such a large gift, none of whom are gamers. I expect it to keep selling like hotcakes.
In addition, I didn't anticipate buying more launch titles for it other than Your Shape which I got as a gift, but the combo of good times with KAdventures! and a buy 1/ get one at 50% sale on Amazon sold me on Sports and Dance Central as well.
