The following is a re-enactment of the mysterious and sudden failure of Megan Lavey's MacBook.

It was the evening of Tuesday, July 14, 2009. Megan Lavey heads out to the movies to watch the eagerly anticipated Harry Potter and Half-Blood Prince. But the excitement of the night was short lived.

Upon her arrival home, Megan found her MacBook in an unconscious state. She tried several attempts to revive it: plugging it and unplugging it, removing and reinserting the battery, as well as performing an SMC reset. However, these attempts proved futile.

In a last ditch effort, Megan made an emergency visit to her local Apple store to meet with a genius. They had both good news and bad news. The good news was that they identified the problem with her MacBook (the logic board) and could save it, but -- and here comes the bad news -- could cost up $750 to repair. What's worse, Megan didn't have AppleCare coverage. In a state of shock and sadness, Megan leaned on the shoulders of her fellow TUAWers, each of whom offered words of encouragement her:

Chris Rawson: "My wife's mid-2007 MacBook is having the exact same issue right now. Luckily, it's covered by AppleCare, and going to the local repair place ASAP."

Erica Sadun: "":( :( :(""

Sang Tang: "Hey, this would make an interesting post. I'm going to write something on this."

There are many Megans in the world, and each is faced with the difficult task of deciding whether or not a repair is worth its cost. It's also times like these that one regrets not purchasing AppleCare, for often times repair costs outweigh the cost of AppleCare. And this raises the question. Should you purchase AppleCare? Several months back, TUAW's Robert Palmer penned a piece on why he believes AppleCare is worth it. This post expands upon that and provides examples of when AppleCare is and isn't justified.
