I wanted to say that after having squeaking hinges on my MacBook (black of course only has this issue) for about 2 weeks, I decided to drive down 40+ miles to the closest Apple store to repair it. I recieved my repaired MacBook last friday via FedEx and I'm happy to report that the hinge squeak problem has been fixed by Applecare. I'm posting this thread to encourage MacBook owners with similar problems to go out and get it fixed.
