Have you compared using screen protector films to just bare screens? I have, and I prefer bare screen, because 1) no decrease in capacitance 2) no air bubbles 3) no crud buildup around the edges 4) easier to polish the glass crystal clear than the film.
Until the films can be made with carbon nanofibers or something to eliminate screen cracks when dropped, I won't be using them again.
