Kinect: 2 songs in free demo, cool ...

Kinect Adventure (the game that comes with Kinect) comes with 3 demo games: Driving, Dance Central, and Aerobic.  The Driving game and Aerobic game are kind of lame, but the Dance Central game definitely worth trying.  The demo version comes with the 90s dance oldie "Poison" and Lady GaGa's "Poker Face", which should be enough for some family fun.
