Buy it! I always do, and wind up using it 3/4 of the time.
3/4 of the time, really? Maybe we need to start buying reliable products if these things fall apart in the first 3 years with that kind of regularity?
If you doesn't buy an apple care, you will have to go to the company yourself with your iMac twice. It is really convenient since iMac 27" is really big to delivery.
I just looked it up because this didn't sound right. According to Apple,
Onsite service. Onsite service is available for many desktop computers if the location of the Covered Equipment is within 50 miles (80 kilometers) radius of an Apple Authorized Onsite Service Provider.
So, good luck in a lot of places.
Anyways, one of the problems with this sort of discussion is that people show up saying "I always buy it and it's paid for itself....". Meanwhile, the guys who have never used it never show up.
When I sold the cheese, salespeople would always say "yeah, I see these come back a lot, just the other day..." Of course, they'd forget that it was a 30-day return or that they were an authorized service center so where were the products going to go? And what is a lot anyway? The reality is that they had no idea how often products came back and even if they were being honest about the situation, not very likely based on what I saw, their observations were useless in the grand scheme of things.
Note: I'm not saying anyone here is lying, just pointing out that when I sold them, the pressure, and the rewards were such that, it was very hard to sell them honestly. I was probably the worst cheese salesman ever. Even at an Apple store, where they don't have commissions, I bet there is pressure to sell them, it just takes a different form.
A couple of other points, I have a Discover card, so that doubles the warranty period up to 1-year. Also, I'm a government employee so I get AC on the iMac I'm looking at for $119 vs $169. Interesting!
