Many people has exchanged several times and got the same screen with lines. Other people has pass the 14 days return policy and choose to live with the "lines" for now and see what Apple's response is to the issue.
If you have a "GREAT" screen, congratulations. I seen couple perfect screen 1.6ghz at different Apple stores, but none in 1.86ghz SSD. I wish I can have one of the perfect screens.
However, I don't think it's fair for you to post in several threads calling us obsessive, when we are just expressing our opinions and wanting to know the latest info from other macrumors members on the issue.
