I managed to put 2 small scratches on my screen i'm guessing from the stylus, 2 days before the clarivue came in. After applying the screen protector I can't see the scratches anymore and the screen is stiffer, more like iphone's capacity screen stiff. Still very responsive.

BTW, I would stay away from those rubber screens like zaggs and invisible shield etc... they grab your stylus. Just my opinion...
