I have a Rev A MBP which is approaching the two year mark. I have AppleCare, and i'm finding many issues as of late. For starters, I have a ring of circles in the middle of my LCD, which from what I understand was an issue before with the PowerBooks. Also, I have aluminum wearing off of my case. Please see the pictures below... Is this considered normal wear and tear? It looks awful. Any possibility that either the screen issue or the case issue would be covered by AppleCare? Thanks!
