My wife's late 2013 15" screen protective coating is starting to peel off. I tried to capture it but it didn't come out too good. You can see the white spots on the left edge of the screen. We bought it in January 2014 and Applecare is good till January 2017. Do you think I should take it in now and hope they replace the screen or do I wait some more to get worse? Do you think I have a case now?
