Welcome to the club. I started my Linux and BSD journey in ~1998 and I haven't really touched Windows since ~2001 except for the occasional brief interaction.

I've never missed it. Like at all. There have been instances where some piece of software didn't have a Linux alternative, that's mostly been a mild inconvenience. There have been cases where it's been a serious problem too, such as when my ever-so-wonderful government decided to start using e-ID which only worked on Windows (thanks, Wouter from grep.be for fixing that).

Mostly I enjoy how I'm in control of my machine, instead of having to rely on a bunch of untrustworthy moneygrabbers who seem hell-bent on making the worst possible decisions at every turn.
