@darth I'm 100% Linux for my desktops (including main desktop), ChromeOS for my main laptop (with Crostini and Debian :D ), and MacOS for work.

Zero Windows but I am contemplating installing Windows on a drive from a new desktop I'll be getting. Occasionally I do need Windows and I do have a VM running on the Mac, but it isn't juicy enough to test some of the Windows software we develop at work.
