Hi there, What am I to expect as far as service and support goes if I purchase the AppleCare plan on my iMac? If my iMac dies, will they replace it? If there is user-inflicted damage, will they repair it? What real-world support have you folks seen from AppleCare, and is the plan even worth buying? I ask because I've heard many horror stories about these extended warranty plans... they sound good in theory but when the company is pressed to back it, they fall apart.
