Does anyone have any recommendations for keyboard covers for the new macbook? I searched and couldnt really find any. My new alum macbook's keys are starting to show dirt/oil even though I dont use it too much. I know with my ibook G4 i had a problem with the letters on the keyboard fading after use, so Id like to get some protection for my keyboard ASAP. Any suggestions for good keyboard covers that would fit the new macbook?
