Mac is a Unix-base (unlike Windows) with good first party support.

Being able to seamlessly share a clipboard w/ my phone, iPad, and computer, or using an iPad as an extra screen or pen-on-screen tablet? It feels amazing, and a true reward for living within this walled garden.
It may not be the end all be all of OS but it has a good feel, good design, and a proper terminal shell.
(to be fair Apple probably gets a boost in perception for avoiding the "race to the bottom" of cheap ass PCs. Just the thought of trying to live with the trackpad of one of those $400-wonders makes me curl up! Like, I'm sure there are great quality hardware PCs out there but they're about as expensive as the Macs)
