lol, are you calling n900's touch unresponsive? you must be joking, it instantly reacts on a slightest push while having the great feature of not reacting when you just touch it(and unintentional touches are something that happens to everyone, you lie if you say that they dont happen to you, and that is something that i hate whenever im using a capacitive screen)

ease of use is identical...especialy if you are talking about gestures and multitouch, because those two things have nothing to do with touch technology, multitouch resistive digitizers exist for years(althou i dont see much use for MT except for games when HW keys are unavailable)
