I had Zagg on my iPhone. After a while, I ended up removing it. The only thing I use is the apple bumper. It shows the iPhone beauty. The MBP has beautiful unibody case. I am just afraid that it will get scratch up. I will be bringing back and forth home and office every day. I guess, if I worry too much, I will have to get some thing that I can take out and put back as I feel like. Is there a good super thin case anyone can recommend? Thanks everyone for sharing your thought on the protection subject.
