Also, don't forget that if you bought it with a platinum and above credit card, you automatically get a free extension of your warranty (covering the exact same things as the original warranty) through your credit card company. AND often you can purchase another three years on top of that for about half of what applecare costs. No free tech support, but other than that it works better imo because unlike Apple, VISA/Mastercard don't question whether you actually have a problem.It also covers batteries and has a no lemon policy which means that if you have to repair three times (not 100% sure about the rules for this) they will replace it with the equivalent new machine.
I've stopped getting applecare and only use VISA extended performance guarantee - it's one of those truly great services that few people seem to know about (maybe that's why it's so great still)
