I “switched to Linux” from Windows 2000 but I have also had machines running with Windows and macOS during that time. My last work computer was Windows 11 ( but I hardly used it ).
Hard to really put into words what kept me in Linux. At times, it has required work and knowledge Windows would not have demanded of me. At the same time, Linux has been largely free of “nonsense”. It just always felt like home.
[ Edit: thinking about I more. I have used Linux since 1992 and honestly moved from primarily OS/2 to mostly Linux. I really liked Windows 2000 though and used it well into the XP era. ]
