Well this is a pretty interesting article. These guys performed a test by simply using a drawing app to draw diagonal lines across the screen of 4 phones. They tested the iPhone, N1, Droid, and Droid Eris.
In the test, if you draw your lines slowly, you'll be able to tell how accurate the screens touch ability is. If your lines are very straight, it means that the accuracy when pointing at things and typing on the keyboard is a lot better.
Anyways, the winner in their test was the iPhone. N1 and Eris tied, and the Droid got dead last.
