so i have a question... i bought a rev. a aluminum 15" powerbook back right when they first came out. within a couple weeks i noticed i was a victim of the whitespot problem. however i didnt feel like giving up my computer for whatever amount of time and didnt fix it right away. i had applecare so i knew i had 3 years to replace it. anyways, i still havent replaced the screen. so my question is, if i were to do it now, or in the future, what are the chances i get one of these nice new displays??
