My wife has been a mac head her entire life and is a technology consultant both Apple and pc. She insists we always buy Apple Care with a new Apple product. You can get tech support over the phone for that additional year. I would certainly recommend it. What is the least costly mistake to make, to have it and not need it or to need it and not have it.
I've had 5 Apple Laptops, and 1 iMac. I only purchased the Applecare once. I ended up selling it. IMO I wouldn't get it, since you're covered. If you feel you MUST. Go to eBay and pick up an unused one for cheap.
