The Kinect is a very interesting piece of technology. Because it is REAL. You can buy it, you can use it. Of course, it is not the end of the mouse and keyboard as we know today, because it is just the first step, but it is here, not just a prototype in some lab.<p>That said, I don't think it will replace mouse and keyboard, because the way we interact with our computer is based on the periphery, the mouse and keyboard. Without mouse buttons, we can't click on something that good (there are possibilities for clicking with a gesture, but it sucks, at least at the moment). We can't type text with gestures, perhaps we have to dance letters? :) So in order to use motion based computer interaction on a daily basis, we need to invent some new interface link between the computer and our body. The Kinect is a very first but also a very good step in the right direction, because it is here, it is open, and it is not too expensive to use it. And it is a lot of fun to play with :)
