Liz, in the past I would agree with you and skip AppleCare for your iMac. (I think that ALL extended warranties are rip-offs, particularly those sold by car dealers and places like Circuit City. ALWAYS be sure to read the fine print if you find yourself tempted to buy...)
However, as a long-time Mac user I have witnessed the gradual decline of Apple hardware reliability. In the not-so-distant past Apple won the hardware wars hands-down... Apple was expensive but Oh So Reliable, while PCs generally tended to exhibit the reliability of a Yugo.
But as Apple's prices have gone down, so has the quality of the hardware.
And while Consumer Reports claims that Apple is the most reliable computer hardware out there, relatively-speaking, Apple is keeping company with PC manufacturers that aren't very good themselves, quality-wise. It's all
relative, know what I mean? Consumer Reports and others of its ilk are grading on a
curve, so take those grades with a handful of Fleur de Sel.
Granted, LCD iMacs seem to be more reliable than Apple portables. But consider this: replacing an LCD or mother board will run you around $500-$600 after your one-year warranty runs out.
Even replacing a dead drive will be upwards of $200, unless you happen to own one of the mid-generation G5 iMacs that have the easy-to-remove back. In that case you are only out the cost of a bare drive and 10-15 minutes of your time...
I have been known to troll other Apple forums
and it is distressingly common for Macs of all types to suffer these kinds of hardware calamities at between 1-3 years of age. Sometimes it is a design or hardware flaw and Apple will set-up an extended repair program for those "lucky" enough to own an affected Mac with a winning serial number. But a lot of time time it is just Bad Luck... Have you ever looked inside your iMac? How about a MacBook? The parts are all crammed in there, making lots of heat and being made to work at incredibly close tolerances. It's a jungle in there! (Minus the humidity, hopefully...) And sometimes Stuff Happens. (Hey, we're a family-friendly Apple forum, aren't we??? The scatologically-inclined among us will have to go elsewhere for their kicks...)
An AppleCare plan for an iMac at
The L.A. Computer Company will run you $120 (the suggested retail price is $169.) That's ten dollars a month or 33 cents per day... or .0000456 cents per second. To put it in terms that some folks will better understand, it's the equivalent of two Starbuck's Crappuccinos a month.
What A Deal for a little Peace of Mind!
Now, I may gripe and grumble when I pull those dirty, rumpled bills from my pocket, but I have come to consider AppleCare to be an essential component of the
actual cost of purchasing a new Mac, along with extra RAM.
