yeah, definitely buy the apple care. way back when with my pismo powerbook, i had to send it back 3 times for repairs after the 2 year mark, they eventually couldn't resolve the problem and sent me a brand new powerbook!!
also had a monitor issue that was free to be replaced for us and an imac G5 HD crash.
sounds like a lot of computer problems from one company but given the multitude of computers we've owned over the years, relatively our problems have been minimal and the ones we did have were solved for us without charge (after paying for apple care, of course).
