Actually I had a Mac mini with the touchpad and the damn thing disconnected three times a day. All my input devices have wires now and the stick out of the right places.

Touché. But seriously, most people who want to run Linux on Mac want to do it because they like Apple's laptop hardware. If you want a compact Linux desktop then a NUC should probably serve you just as well. Or at least, this was the case while Apple was still using Intel chips. If Apple Silicon lives up to expectations then I suppose there could finally be a compelling reason for running Linux on a Mac desktop.

To be clear, I'm not saying that there couldn't possibly be any good reason for wanting to run Linux on a Mac desktop. But desktops are already a niche product for Apple, and people who want to run Linux on Mac desktops are arguably a tiny niche within a niche.
