Multi-Touch screen research

I'm starting to believe the next big thing in computing is going to be touch screen control of your PC. Most touch screens on ATM's or bar-top arcade machines only allow a single point of contact. Researchers have now developed a touch screen that can sense multiple points of contact simultaneously. This doesn't sound like a big deal until you watch the video on their webpage. Even with a mouse, you can only interact with the screen at one point. Watch how easy it becomes to sort pictures or resize a map with the multi-touch screen.
