I'm looking for opinions on the iSkin Protouch and Moshi keyboard skins. I've read user reviews, and both products are rated as either the best thing since sliced bread, or a piece of crap. Also, most reviews are based on short term use, so I'm looking for feedback based on longer usage. I have a new 15" MBP with the hi-res anti-glare screen, so non-contact with the screen when closed is important, along with protecting the MBP.
