Yes, Gorilla Glass can scratch - Trophy had it, and twice I ended up with scratches that I have no idea how they got there. One of them was about two inches long. I am NOT a person who carried a phone in his pocket, but in a belt case, so it wasn't keys or coins, so I've been puzzled as to what happened. I don't know how much better the GG2 is, but my point is that even though it is resistant, like the others have said, it can be scratched, and is more likely to happen inadvertantly, so a protector is a wise investment. It will change the feel, which is why I never put one on Trophy, until about a month ago. What changed my mind is this - I'd had screen protectors on prior phones, which were all Windows Mobile with stylii, and were rubbery feeling, which was nice for using with a stylus, but not what I wanted for finger. I had no idea they had nice feeling protectors for finger use until last month when I changed my step-daughter's screen on her Arrive, and what we bought for her phone came with protectors and I felt them, so I put one on my Trophy. It changed the feel slightly, but not enough for me to forego the protection on a much more expensive screen.
