Actually, I later re-calibrated it using the stylus, to make sure it was as precise as possible. I think this did help to some degree, although I think getting a better feel for it is helping as well.

That said, there are some times when it is particularly unresponsive - when I go to Settings...All Settings... The icons that show there for the different items are sometimes very unresponsive. I don't know if it's the touchscreen or the OS being unresponsive, but I suspect the latter. Most everywhere else it works better, although I do have to zoom in using Opera to click on many small links.
