Still doesn't necessarily make sense economically... most of those things are a cinch to replace yourself with a $10 electronics screwdriver set from Radioshack. From iFixit.com, my model MBP: Fan - $50 Battery - $100. Keyboard - $85. The logic board is probably a bit trickier, but I don't know how common those failures are (a Google search on any mass market device will show a lot of failures... .1% of a million is…
Those replacements would be around $315 compared to $249 I paid for it. Also, more things can break. It also saved time. If one has to do dollar-to-dollar comparison for $10/mo service, they aren't ready to buy a $1200 laptop. Just because I can rip apart my laptop and can reapair it myself doesn't mean I shouldn't buy service which cover failure of it's components. That's like saying a doctor shouldn't buy medical i…
Also, I was stating a case where 3 parts go bad on the laptop, which I think is pretty pessimistic - I've only had a fan go on my MBP, and that was under exceptional circumstances (my apartment was filled with very fine abrasive stone dust). It paid off for you, but as with all insurance plans, the odds were against it paying off for you, unless you are much riskier to insure than average.
Furthermore, I don't believe normal battery wear and tear is covered under applecare.
