On the software side, Apple has the unique position to force every developer who cares about their user base to rebuild their stuff for a completely different CPU architecture.
M1-based products are anything but overpriced. The Air’s price is comparable to modern flagship smartphones.
At this point in history, you can't avoid Apple's ecosystem if you want to use their ARM-based laptops/desktops unless it's a hobby of yours. And it's sad, because this is the best hardware I've ever owned.
Retina Display when it first arrived was literally THE reason I started switching to Apple ecosystem as it was exponentially better to look at that screen, and I'd even pay more for a 4K display on a MacBook if they brought it.
They're not EliteBook/Thinkpad tough, but they're more than enough unless you're going to handle it rough.
I can calibrate a screen regardless of the OS I use with the help of a good calibration device, and having a good panel is a good start for that. On desktop, there are possibly better panels for pure color accuracy, I won't argue that.
OTOH, on the portable space, their hardware formula is pretty robust.
Worse, it would take some time for me to even trust Linux on M1 laptops to not fail exactly when I need it - that's the nature of reverse engineering. Since they don't have the specs, the only real test is lots of people running it for some time and reliability is more important to me than specs.
As for monitors, Apple's colour advantage is more than good calibration - the entire ecosystem can handle 10bit HDR. That's something AFAIK you won't get elsewhere.
For example, take the monitor - there are monitors with higher refresh rates or more resolution (Retina does 'only' 6K). Also, Mac OS colour processing has no good equivalent elsewhere, so you won't see as much benefit from Apple's monitor without Mac OS.
