don't get the negativity. if you don't believe in it don't get it.
i for one have bought apple care for every apple device i've purcahsed and my business has purchased.
it has always ended up saving me money.
on 4 mac pros, and 4 mac book pros, 3 iphones, 6 apple cinema dispalys. and two ipads.
3 mac pros had problems whcih exceeded teh cost of apple care. one of them had problems 3 different times.
1 ipad1 replaced because of dead pixels. and then replaced again because of light leakage.
2 apple cinema displays eventually started flickering and were replaced by apple care.
3 macbook pros were all repaired by apple care. one had the entire screen housing replaced because the isight didn't work, the logic board and optical drive replaced.
So for me Its saved my ass a bunch of times. For others i can see they've never had issues. To each his own.
I've ordered two new iphone 4s's with apple care +. Its cheaper than the carriers insurance.
