Due to the highly integrated and difficulty in parts and repair process, I would get Applecare for any Apple laptops. We are no longer in the age where we can simply replace the RAM or drive ourselves, unfortunately. And the lack of schematics available for 3rd party repairs made repairs of Apple laptops more difficult.
While this is true, I've gone through 8 personal Apple laptops and had 3 out of warranty repairs, all were covered by extension programs
1) Logic board replacement for 8600GT issue in 2008 MBP
2) Screen replacement for delamination in 2013 rMBP
3) Top case replacement for unresponsive butterfly keys in 2016 MBP
All my work laptops have had AppleCare, of course, and none have had an issue.
Personally I feel like it - and just about any extended warranty - is tossing $$ into a furnace. Over your lifetime of ownership as a consumer it's in aggregate a big loss financially to take this tact. It's a fact... it's a 'product' they sell. They make money off of it.
If you're exceptionally hard on or clumsy with your electronics... maybe. And if you buy a more top of the line config it makes way more sense as it's a fixed cost. But for someone like me who tends to buy base models and upgrades more often (again, a more prudent move financially speaking if performance matters, considering how well these machines hold their value)... holding off from purchasing it 2x virtually pays for every 3rd upgrade to a new machine.
As much as Apple laptops have become closed box systems, they also appear to be better built than ever, and when they eff up, there almost always is public outcry and a program to fix that extends way past the warranty.
