I decided to run without a protector and it cost me. I've got a line of small scratches parallel to each other along the line you where you would use your finger to scroll down the screen. I don't know if I had some sand on my finger one day or what. They aren't deep enough to feel, and if you clean the glass with microfiber they disappear from view. But once the screen gets the slightest bit of fingerprints and oil on it, they show up again. I'm debating whether to try to polish it out before I put a protector on. Does anyone know if our screen has any kind of anti-fingerprint coating I might mess up if I do?
