> EDIT: Will someone explain what this theoretical 'non spec' thing that matters is? The Apple logo?
Mostly the OS. I don't cringe before plugging into an unfamiliar external display. The touchpad isn't so bad it makes me feel like I have to carry a mouse if I plan to use the device for any length of time. The built-in "office" suite of apps are my favorite I've used, anywhere. Preview is indispensable for working with PDFs—I've never even known PDFs to be more than barely tolerable to work with outside Apple's world. It's Unixy, so many of my preferred tools work natively on it. It has lots of built-in stuff that's less convenient or works less well on Linux (modifier key remapping, screen sharing, and more).
I've been around the block with Linux on the desktop. Around and around and around, in fact. I could tolerate Windows—not as a work OS, but for gaming, anyway—all the way from 3.1 to 8, but 10's aggressively unpleasant. Now MacOS is the only desktop OS that doesn't drive me to swear at it multiple times a day while using it. That's worth some money, when I have to use some OS just about 365 days a year.
Touchbar's beyond dumb and into "harms UX" territory, though. The keyboard two generations ago—on the fatter Macbooks that still had disc drives—is noticeably better than either since, and the butterfly keyboards are awful. Unfortunately every other option is so much worse that they can afford to screw up badly for years on end and I still can't bring myself to switch.
