Well, colour me intrigued. I like the idea of rewinding and screenshotting games and I like the idea of making a single player game like Fallout or Mass Effect a shared experience. I assume the feature works without you actually playing the game (ie a video stream?) so you can see a friend messing about on a game and decide if you want it. I'm not letting anyone take control of my games though wtf.

Nothing that's been announced so far has made me want to get one at release though. Couple of games interest me but nothing is leaping out as something I MUST HAVE. We'll see what Microsoft have to offer.
