I know that Apple has an extended repair program to fix the white spots that people were getting on TiBooks and Rev A 15 inch PB screens (there is a thread about it at https://forums.macrumors.com/showthread.php?postid=1361215#poststop). Apple claims to have fixed it with later revisions, but my Rev C 15 inch PB seems to have the exact same white spots, and, needless to say, I'm quite disappointed. I'm wondering if other people with later machines (Rev B, C or D) have this problem. If so, has Apple looked after you as they should?
