AppleCare provides 2 benefits: 1) extends the warranty to 3 full years, 2) extends technical support for the computer and Apple software to 3 full years. Without AC, the warranty is 1 year and technical support is 90 days. If you are new to the Mac family the technical support alone is likely to be worth the price. I'm a 30 year vet of the computer biz and an IT specialist and I have always bought AC for my notebooks - not my desktops, just my notebooks. If the LCD, keyboard, or logic board goes down, that alone will pay for the AC.
