Me too. Had to go back to Windows at $JOB recently and find the experience... unpleasant, to put it mildly. I guess once you get used to a certain way it's difficult to change it. Hoping to get rid of Windows again soon. Can't imagine using W11, from what I've seen.
Same situation. I've used Windows over the years for playing some games with friends, but even that had become something that I can do entirely in Linux too.
Call me a fool, but I'm also loving Gnome 40+ and GTK 4.6+, especially with libadwaita.
I also left Windows in the mid-1990's. I have tried looking back from time to time, when it felt like it would make life at work easier. The thing is, it never does. That doesn't really say anything about Windows, since it has improved a lot over the years and my reasons for leaving it are no longer valid. It says more about what I am used to, how I expect to get things done, what I am willing to put up with, and what I am not willing to put up with.
I've been trying since the 90s. I became a Linux expert, but I've still failed to switch to Linux. The reasons are probably: (A) The mythos of Microsoft collecting all of our information and storing it until the end of time seems incredibly unrealistic to me (B) I don't like friction, Linux is full of unnecessary friction to get anything done (C) Lack of commercial programs, and a user base that is actively hostile to the idea of commercial software (FOSS is better, don't you know?) and/or hostile to changes that would make commercial software more viable on Linux (D) Difficulty in actually fixing things, which I have tried to do many times (the Linux ecosystem is built from some truly awful codebases) (E) constant glitches and bugs, which I don't have time to track down and fix
Same story here, happy Linux user since the 90s... at home on family computers and at job. It's like choosing Netflix vs HBO Go - takes a few days to find your favorites, once you get it you are all set and don't worry anymore about the competition.
