I have kept my Droid since launch day in my pocket with nothing more than a tube of chapstick, and it has some fine scratches on the screen already. I noticed this last night and tried to put on the Verizon protectors I bought and then never got around to putting on. That was my experience, and I ended up trashing the first one. The second one is on now but it bubbles and isn't sticking to the corners. It's really hard to put on just right. I didn't try the third last night as I was tired and getting pissed off. Maybe tonight I'll give it a shot after trimming a tiny amount off one side.
