"more meretriciously sentimental than a whore on wharf", and that whole paragraph basically, is worth $43.40 at least ( I'm kind of surprised it didn't make it into the tags, this being the Billfold and all). Great, great article.
I had this exact conversation with my husband in the Mac store this weekend. He decided to go for the AppleCare, because his last laptop's screen died in the last month of his warranty, saving him around $400 bucks (or so the geniuses said) for repairs. We're in Canada, and the package he got this weekend was only $199 for three years. It's still better than all the warranties I bought for my crappy PC laptops in the mid-2000s, which ran me an $300 and ended up not covering "accessories" like the adapter (blew twice) or the battery (only held ten minutes of charge after two years of use). I think more than anything, though, you guys are right; it's about peace of mind, not the actual dollar amount saved in case of repairs.
