Thanks for your input. I may buy AC through a third party as I don't really need accidental damage and I can get it for $100 less. I think at this point, my main concern would be battery swelling and replacement, i think, is $129, so for another $150, i'm pretty well covered.
Third party-priced AC is. a
Nobody ever asked that question before, so here's the definitive answer. Yes and no, it depends.
If consumer protection law is weak in your state/country, then yes because you want to know an expensive product is covered.
If Applecare is a viable proposition for Apple, and it must be or they wouldn't do it, then overall it must cost customers money, so no.
First, we don't know what Apple's experience with any given product line/model is. I think you're obviously right that it's INTENDED to make Apple money, and that only happens at customers' expense. So if the sample size is big enough, absolutely you're right, it costs customers money.
On the other hand, for any individual customer, the question is only whether YOUR device or machine needs service and YOU make or loose money on the AC bet. Back in early iPhone days I always bought AC. By the time I got to the iPhone 5 I realized I was getting hosed and stopped buying it and never have again - have never had any issues.
I did not buy it for my 2013 rMBP and had no issues, so money saved again.
I did buy it on my 2012 Mini. It had a serious issue 35 months into AC and that was fixed for free - so money ahead.
I also bought it for my earlier early 2015 rMBP. It lost both speakers and the trackpad, a very expensive repair, fixed for free - so money way ahead.
I bought an AW last month. I know that I bang into things, and given screen replacement costs and the cheap price of AC+ for the AW, I bought that without any hesitation and I know I'll be money ahead. In the past 18 months I have had serious repairs on two Rolex watches and an Omega, repairs that cost more than some people spend on a car, so AC+ on the AW is a total no-brainer, but I am probably an exceptional case there.
I'm typing this on a "new" early 2015 rMBP. If I don't return it I think I will buy AC+, which I wish were only AC since I'm very careful about drinks and drops and things like that with my computers.
You pays your money and you takes your chances?
