AppleCare for a 15" MacBook Pro costs $349. which seems steep to me for another two years of coverage. I have no sense of how reliable these machines tend to be since this is the first one we've had. My daughter got it for grad school and it has been trouble free so far, over six months now. She was asking me for my advice about whether the warranty is worth the money versus taking the chance and having to foot the bill for a repair herself if something goes wrong. I'd expect a battery failure or hard disk failure to be the most likely possibilities there but you never know. I don't know what repairs for those issues would cost for a MacBook Pro either. For my own iMac the decision seemed pretty easy. AppleCare was significantly less expensive for my machine and I bought it for the peace of mind. I don't know if I'd have done it for $349. though. Maybe. Probably I'd have come here with this same question posted in the iMac forum. So I'd appreciate any and all advice and feedback about reliability in general for a MacBook Pro 15" purchased just before the retina display models came out. Thanks a lot.
