Kinect as a web browser controller
Here is a more concrete - and amazing - application of the Minority Report fantasy that the Kinect enables.

This is clearly one controller that is not going to stay forever tethered to an Xbox 360, as Microsoft may have originally intended it to. We expect to see even more exciting ways to use a Kinect to control all kinds of things in the future.
Mayble touchless typing is around the corner.
