I just got a new replacement storm from Verizon, the one I'm returning has a crap load of dust under the screen. So, I decided to see how scratch resistant the screens really are. I got a pair of scissors and went to town on it.... These screens will not scratch!
Here's a video of my trying to scratch it:

P.S. Now if RIM can figure out how to keep dust out of it we would have it all..lol
