Don't listen to someone just because they have had THEIR computers for 20 years and didnt need it.... Almost everyone could use applecare, it is a great investment and is WELL worth the money you spend, it really does keep you from worry when problems occur, I would almost suggest trying Pro Care....its an addiction and its 100 a year, but they treat you like royalty, they repaired my computer in 2 hours and then called me to pick it up.... Good luck
Ummm...how about we look at things from a statistical perspective instead of an emotionally charged one?
Fact: A macbook pro costs around $2000 +tax for the base model.
Fact: Applecare on a macbook pro is $350 from Apple, and less if you buy via ebay. I'm going to be simplistic about it and assume $350.
Fact: Hardware that is likely to fail is most likely to fail within the first year of a product's lifespan.
Fact: Applecare is a product/service like any other; its end goal is to make money for Apple.
Fact: Apple has a profit margin of around 50% on Applecare. The hardware margins are around 30%.
Fact: Most credit card companies offer free extended warranties (mine does; one extra year at no cost to me-plus I get 2% cash back on my purchase

).
Now, if we examine all of these facts objectively, we see that Apple sells Applecare on mbps for $350, with a profit of around $175 (50%). This is after having retail employees sell it to you, after creating the system which maintains records, and after the legal expenses involved (probably the highest cost of production).
With these facts alone, we can surmise that you are statistically only likely to need a total of $175 worth of coverage on your mbp, for which you must pay $350. Sounds like a bad deal to me so far.
Now, we all know how insurance works, so I'm not going to bother with actuarial science here (especially with the way I suck at math

).
The odds of your particular mbp needing extra work between months 13 and 36 are incredibly low. The fact is that because Apple only pays out $175/mbp on average, the odds of your particular notebook needing an expensive repair (or an entirely new machine) are low. If we do some quick math, we find that $175/$2000=8.75%. In other words, the odds of your notebook needing a complete replacement or extensive repairs is less than 9% (less when we consider the others administrative costs of Applecare).
So, is it worth it? I'd say it isn't. With the free year of extended coverage I get, my odds of being covered are quite good. I feel no need to shell out an additional $350 of "insurance" that is statistically unlikely to help me.
