You guys really aren't getting that this technology is completely different than Vivid and Mandala (I was there back then and we used to sell them) and it's not eye toy.. Kinect is a camera, and motion sensor and a microphone with all very intelligent software driving it.. It has much the same type of technology that the TSA uses in airports. Kinect was shown a few years ago as not a microsoft product, microsoft bought it and transformed it (it was a bunch of boxes positioned at different points). The coolest part of it is Kinect ID.. It does facial recognition to log into the xbox live network, and I can walk in front of my friend's xbox and it recognizes me and we can play together (up to four of us) on the same system and it knows me.. (On my system or my friends).. The scanning function is pretty cool too..
My laptops** already includes facial recognition feature during Windows logon...
