I bought an Incase Hardshell for my MPB 15", and while it looked really nice it was nearly impossible to get off! I knew it would be hard, but I didn't think it would be that hard. After reading a ton of suggestions to get it off I ended up having to use a butter knife wrapped in a kitchen towel. The knife left a small scratch but it isn't a huge deal. Took about an hour to get off. Just wanted to warn people who were considering these that they are hard to remove! I probably wouldn't have put one on if I had known, just a heads up!
