@stefano@bsd.cafe probably about 20-25 years ago I started looking into using Linux, and tinkered with a few distros (Debian, Fedora, Arch, openSUSE) in dual boot set up or as VMs, to test the waters of having a system I could configure for me, not configure myself for it.
Ultimately I made the absolute switch about 15 or so years ago (Arch...btw, and servers set up with RHEL based, Debian or FreeBSD) and haven't looked back.
I still have a Windows VM which I can spin up for those times I need it, but it's pretty much just 2 uses I have for it, I can do everything else on Linux or BSD.

Of course, I still have to support windows as part of my daily work... But of course I provide solutions via Linux or BSD
