Hi, Three days ago Apple replaced my early-2011 MacBook Pro with a late-2011 model in store due to multiple failed attempts to fix my machine. However I just discovered a stuck pixel on it. I know Apple has a policy on that, but I also know that people whose machine was in the 14-day exchange period were able to swap for a new one. Given that I didn't purchase the new MacBook Pro (again, Apple replaced it), and the warranty has been extended, should I take it to the Apple Store and ask for a fix, or a replacement? Thanks a lot.
