Great Wiimote Concept With A Standard Laptop

We have put posts up in the past about the Wiimote conversion as a whiteboard, and it seemed to work well.  This video takes a little different spin. They use that same technology on a regular laptop.  In the video, the user is using a standard laptop with a Wii remote mounted out of camera view to create the same ‘touch’ experience we have seen before.   Anybody else think that screen is probably a scratched up mess by now?? I think it will be interesting to see if anybody expands on this idea over the next year to two.
