On all of my machines bar one, windows is completely gone. I have a simrig, currently running win10, but the hardware there, simucube base, simucube pedals, require some drivers I don't believe exist under linux, and/or don't work properly, and then there is iracing with it's easy anti cheat usage, from my understanding I'm screwed there as well. So it'll live on Windows 10 until the day iRacing stops supporting windows 10, or start supporting linux.
after having written that, I wonder if the simucube tools will just work under linux anyways, the UI is all written in QT, maybe simucube has/is developing linux drivers, given they're finland based :) .. I'll need to test it out
