From what I've read, a screen protector is not necessary. That being said, I have one for peace of mind! Especially on those occasions when the kids leave stickyish fingerprints all over and I can just wipe away without worry. Edited to add...if you do go for a protector, don't get a glare-free one! I ended up throwing it away after about two weeks of frustration. It caused the screen to be very pixelly. I got a nice, clear one. I went higher end, and have been very happy!
