I do all my software development in remote clusters/supercomputers. I’d consider myself a power user. My laptop is for running a terminal, vscode, a browser and the various applications my company requires, e.g. Teams, Slack. So I want reliability, low configuration and maintenance overhead on my part and good battery life. Linux can’t compete on these fronts.

All those pros you list have nothing to do with the desktop environment. Maybe low configuration but you can have that on Linux too.

I totally agree that the hardware and the underlying Unix is decent. Audio on Mac is also way less of a hassle. I am not saying that a power user wouldn't have good reason to chose a Mac, just that the desktop is for me the weakest part of it compared to Linux.

I do the same and I prefer KDE much more than Mac OS X apart from battery part.
