Fedora for my main desktop, mainly because I’ve been upgrading it piece by piece since the stone age, but also because it splits the difference between a fully rolling distribution and a slower one. Most of the tools I use for hobbyist stuff are Linux-native anyway.

I also dual-boot into Windows 10 for gaming. I plan on avoiding Windows 11 as long as I can!

For my day job, I have an office-supplied Macbook.
