I've had the XBox for a couple of months, but I was thinking about how I wanted to try Skype with it in the Kinect since I figured it'd be like Star Trek. It totally is. My wife and I talked to my parents first, then her parents, on a 60 inch plasma going over a surround sound system. It was just about as perfect as can be. The camera would pan and zoom to pick up all the faces it saw in the room and frame them just about perfectly, the microphone worked flawlessly with no feedback...it was living in the future with absolutely no tweaking needed on our end. We just sat in our living room and talked to our parents like they were right there.

That's the XBox's killer app, right there. They need to sell based on that. I consider my experience talking with them worth the $500 price of entry, it was that good.
