I'm a first time Mac buyer. If it breaks, I will have no clue how to fix it. My friends and family have usually helped me with any PC problems I have had, but they assure me they know nothing about Macs, so I'll be on my own. Is AppleCare a smart purchase for me? I don't really know how it could break, but I'd hate to be surprised. Is the warranty only available at the time of purchase? And, finally, is it transferable? If I buy a new Mac before my 3 years is up, can the remainder of the warranty be transferred to my new computer? Or if I sell this Mac down the line, can the warranty go to the buyer?
