Purchase an Apple Display independently of your Mac? No problem. Now you can buy AppleCare for your display, too. Previously, the only way to get AppleCare protection for Apple Display was to purchase the display at the same time you bought your Mac. Just like AppleCare for other products, it bumps your warranty up from 90 days to three years, and covers any accessories included with the display. AppleCare for Apple Displays costs US$99.
