You just described google and everything else people use on the internet.
Kinect (supposedly) is way more powerful than a tracking cookie. Google can tell if I watch a video on Youtube, but they can't tell if I laughed or cried while watching it. They might be able to tell that I'm reading a Wikipedia article about butterflies, but they can't tell that I'm drinking a bottle of vodka and snorting cocaine while doing it. They might be able to tell that I watched The Wire, but they don't know that my eyes were eerily transfixed on Omar's penis that one time.
