You are being way too literal in what I said. I did not necessarily mean waving one's hands around, but rather, the ability to make movements and have actions occur, without being tied to a physical object.
Here is an example, you may understand. the iPhone keyboard - how many people said that it would not work because of the lack of a physical keyboard, and the absence of feedback. However, the virtual keyboard works with some practice. Kinect is potentially another step in the virtualization process of interacting with a computer, without the need to even touch the screen.
See, that was not that difficult.
