In my experience, 3 years is a good warranty period for a desktop. While the rate of a failure may be low, you have to consider that the cost of the warranty is around 7% of the cost of the computer (speaking of the 27" $2000 model which I will be purchasing). Then consider the cost of a small repair on it, many failures will run more than the cost of AppleCare.
Plus as it is an AIO computer, do you really want to deal with tearing it open and risking more damage to it? I certainly don't - but I also don't want to deal with it as my day job is working in I.T. already and the last thing I want when I get home is to fix my own system.
