Something I have been doing on the (singletouch, resistive) touchpads, since they are so inaccurate, I put two fingers on them. The value received by the OS is the middle point between your two fingers. If you only move one finger while touching with both, the cursor moves slower and you can point with more accuracy. On the touchscreens this would have the advantage that you could see the pointer.
