I bought the marware keyboard cover they sell at the apple store because they didn't have iskin or moshi. The issue I'm having is that this keyboard cover sticks to the screen! When I open my rMBP I have to peel the keyboard cover off of the screen. I'm wondering if there is less clearance between the keyboard and screen that is causing it to stick or if it's just this cover. Is there a better keyboard cover for the rMPB?
