I first started running Linux in the early 2000s. I wasn’t solely using Linux, but it was very much a situation where I used it for what it was best at and used Windows for where I needed Windows. Mostly that was for games, but it was early in my IT career and Windows was a skill I needed to build, so I did a lot of dual booting. It really propelled my understanding of computers running and breaking multiple OSes.
I fully made the switch a couple of years ago when I realized I hadn’t booted my Windows install in six months. Linux has come a long way, and has also been helped by so many things being browser-based these days.
I drew the line when my Windows box told me I couldn’t do something even with admin. Kid, you work for ME, not the other way around.
Always preferred Linux over Windows, but I had issues with games on it. I just decided that I wouldn’t play any games that didn’t work. That was a couple of years ago now, and things have only improved since.
My fiance, who is not a technical person, even decided she wanted her new PC to run Linux unprompted, which is a hell of a win for Linux and for me in not having to support a Windows box in the house.
