I have had zero issues with any gestures and a screen protector. In fact the screen is still very sensitive and I had to get used to that coming from a N97 (with a resistive screen and screen protector). That being said Gorilla Glass is pretty sturdy, but I just view the screen protector as an insurance policy. I have it on there in case I drop the phone. The screen protector will provide some level of protection for this and it is much cheaper to replace my screen protector vs the screen itself. I stated on these boards before that I dropped my N97. The back cover got scratched up pretty good as did the screen. I had a Clarivue on the screen and all I had to do was change the screen protector (screen itself was scratch free). It's not like these screen protectors are expensive. For $15-$20 I can provide some level of protection for the screen of a $400+ device. I don't think that is a bad insurance policy.
