Between using my own, my wife's, and best friend's Hero's over the Thanksgiving weekend, it occurred to me that the screen protector really interferes with the responsiveness. My wife has a Zagg, and I had a Bodyguardz. I was becoming frustrated that my phone seemed to be lagging after the update. After using my best friend's unprotected phone, it hit me that it might be the skin. Sure enough, my Bodyguardz went into the trash and I am back to swiping and touching with speed and grace! I'll gladly handle the risk of scratches for the performance I've gotten back! My wife has decided to stay with the "protection", but clearly her phone is not as responsive.
