Well when i type i rest my palms on the bit below the keyboard on the macbook pro. After just having it a day (it arrived yesterday) i noticed that where i had been resting had gone a lighter shade. I only looked last night and not today yet and i was just wondering whether or not that'll go away. I think having your palms there is quite a natural thing and can't see why a user would be expected not to do that. I done it all the time on my old laptop to no visible change (after a year and 4 months). Anybody else had this? Yeah, i guess i just need more information on this if it's happened to anybody and would like to know if there's a solution or if it'll go away.
