In an update to the LucidTouch project shown at last year's TechFest, Microsoft research is showing a smaller display that can be controlled through touch with the input coming on the back of the device. That prevents the so-called "fat finger problem" in which the finger being used for input blocks the display. Without using a rear-input or other approach, it's hard to make touch-screen devices smaller than a few inches in diameter.
