Desktop Linux was historically meant as opposed to server.

Plus, most actual desk tops today feature laptops.

So still a desktop use case: it's just not in "tower" or "mini-tower" or "all-in-one" form.

Linux on a desktop is really quite rock solid (caveat assuming you do research if you are too cutting edge on hardware). Linux in laptops are not as good on battery life and 4k external monitor support has issues (though less so if wayland works on your hardware). The two workarounds they mention for Ubuntu on their page are adding a kernel option to improve suspend battery life, and adding a line in the alsa conf to enable the driver that recognizes the microphone jack they're using...you can hardly extrapolate from those to "desktop linux is teh pits".

Or just buy Linux hardware with Linux pre-installed, with great support for it...

Not if you buy the mainboard and mount it in a little desktop case!
