One of my friends who also has a Sony Tablet S had dropped it a while ago onto the corner of a cinder block. The tablet had the Sony matt protector on it and it appeared that the cinderblock had not only gone through that, but also taken a little chunk out of the screen itself. It wasn't until very recently that we discovered that the tablet had the factory applied screen protector on it and once we peeled it off, the screen itself was perfect. While I have no dobut the matt screen protector helped, that factory applied protector can take a helluva beating it would seem.
I'm actually amazed at how well the actual screen stands up to fingerprints. The factory applied protector and the matt protector are both magnets for fingerprints, but the actual screen itself barely collects any when swiping. I'm now weighing my options for what to do because I now have the factory applied screen protector plus the matt protector on my tablet. I'd love to find a screen protector that minimizes or eliminates fingerprints... any suggestions? While I do like how the matt protector diffuses light sources, I think I could live with a shinier screen so long as it wasn't coated in fingerprints
