A non-technical acquaintance who occasionally asks me for computer help recently switched from Android to iOS (at the behest of her daughter, indicating Apple's continuing mindshare amongst at least one segment), and she utterly hates it compared to Android. From what I can tell, it's not solely because of the pain of changing — it's also that iOS simply isn't as pleasant to use. And that says something, given that she was using a fairly terrible vendor Android previously.
That's just one anecdote, but I wonder how many others there are. How many vi-users will seriously consider switching to Windows or Linux? How many power users will have to switch to Windows or Linux just for more RAM? At what point do people who used to be proud Apple fanatics become sheepish, and at what point do sheepish Apple users just switch to something else already?
And I know as many people who went in the opposite direction, love iOS and love the integration with their Macs (hand-off, etc.). An anecdote is just an anecdote.

Until 'something else' offers: good retina support (including mixing retina and non-retina displays), hardware that works out of the box, long battery life as stated by the manufacturer [1], no spying on user behavior, proper GUI and application sandboxing, low weight, uniform application look & feel + shortcuts, etc.
(I use Linux and Mac, switched from 3 years of Android back to iOS. So hardly a purist ;).)

In any case, the editorial staff are much more capable of comparing laptops, since they not only use a wide variety of laptops, they are also likely to be more savvy than the regular public when it comes to newer features. I'm not sure what you intend to find after asking people who only have experience across a few brands and a few models.
Now, however, instead of having multiple PCs, Joe Public needs one, and preferably one that lasts years. Enter Apple's high-end pitch.
The high resale value is both indicative of the value ascribed as well as a nice perk for buyers.
This probably depends a lot on how you define what Joe Public looks like, but I think you're seriously underestimating the yeoman's effort Apple has put in to become an aspirational brand. Lots of people may make do with a $500 laptop, but lots of them want a Mac.
For better or worse, Apple is as much a lifestyle brand as a technology company today.
