I 2nd that! These screen protectors work extremely well!I got the anti glare screen protector from the Apple store and it doesn't show any fingerprints its amazing I recommend It to everybody I even had the guy at the store put in on for me can't stress enough how well it works. They're 2/$14.95 get em asap
I use this screen protector from Boxwave:
I tried a couple others, but this one was the most fingerprint/smudge resistant of all the ones I tried. The screen does not appear as shiny/glossy, so that's the tradeoff.
