I have AppleCare on all my Macs. I used to think it was overkill to have a three year warranty, but since getting it on my intel iMac which summarily ate its own motherboard, I have come to realize its a bargain to get the fast access to Apple’s support. I have since used it with a misbehaving iPod, a blown power supply on a MacBook Pro, and to get replacement boot disks for my iMac.

My only complaint about AppleCare is that Apple doesn’t make the phone number terribly clear on their website, so I am noting it here where I can find it. The AppleCare Support number is
1-800-275-2273
and they are open 6am to 6pm Pacific time.
