Hey, I have baught a MacBook two-three weeks agoand I an so thrilled with it! I havent had any mooing, squeeling, swelling, or color-changing. I just would like to say two things. One is a comment and one is a question. THe first is, if you are on the fence about the macbooks because of the 'defects,' I would say to forget it, I did and my MacBook is near perfect! The second thing is, how long untill the discoloration appears, or if it appears in everyones computer? Thanks for the help!
