Last year, we reported on Microsoft's Surface Computing touchscreen in our Best of What's New issue. It looks like a coffee table-sized iPhone, only instead of using your fingers on the screen to scroll and zoom, you can use your fingers to grab, move, sort, and rotate any number of items you see. As for the Wii, well, everybody knows about the Wii by now—its controllers use an accelerometer and infrared sensors to figure out where and how quickly you're pointing at your television. Now imagine those two things mashed together—without any external devices.
