The orange peel effect doesn't annoy me. Applying it sucks, so I don't do it. I pay either a Zagg store employee or Best Buy Mobile to do it. Afterwards, I'm satisfied. Though the material makes it harder to slide our finger on the screen, I find it worth it for the protection. I always get the maximum protection (from Amazon, because it's cheaper), so my device is completely protected. Later when I resell the device, I'm very glad I get to say "literally, in perfect condition."
Also, Zagg's customer service is the stuff. I received a recalled version of the iPad 2 shield from Amazon, I called Zagg and it took only a few minutes for things to be done. He said he was sorry, he immediately gave me a code that would pay for the shipping & tax for the replacement, and the new one is headed my way right now. He was really kind and did things in a snap. I took the (recalled) protector and tried "sawing" it with a jagged knife. It didn't do much damage! Then I took a pointy knife and tried seeing how much pressure I could put through the shield before the knife went through. I was pleased! It's not like you'd do things like day to day with your phone, but it is nice knowing you're getting the protection you're paying for.
Not protecting $400+ investments seems like a bad idea to me.
