Personal desktop: endeavour, though I may go back to Debian. I've been using Debian for so long that nothing else feels right, that's a me thing. Endeavour is pretty great.
Work laptop: Windows 11 (stripped down since I have admin rights), unavoidable do to some software I need to run sometimes.
Testing/builds for iOS: M2 Mac Mini
Servers: proxmox, running windows VMs for software I need for work I can rdp into, various Debian LXC's, some Oracle, RHEL, and Debian for work stuff, and occasionally random distros I want to check out.
Bazzite for personal/gaming, currently Arch for my work install. Will be migrating to Aurora-DX for work one of these upcoming weekends.
I still have Windows for the occasional game that doesn't quite work right under Proton and for my VR headset which requires Windows Mixed Reality 🤮. Don't do VR much, so it's quite rare that I boot it up.
I still run Windows 10 on my laptop. I have a few specialty apps that still require it, but I expect to switch to Linux rather than Windows 11. I also run a household server on Ubuntu Linux.
Windows 11. It sucks but I have apps that don't run on Linux, and there simply aren't any alternatives. I dual boot Kubuntu on my laptop and Kubuntu is great. I just wish software compatibility is better
Windows 10 for now. When they EoL it I'll switch to a Linux distro. Not sure what yet. I really like PopOS on my Surface because the gnome interface works well, but I think I'll go with something built with KDE for my desktop
Windows, primarily, because I need shit to just function. And there's no competition to OneNote and Office in Open Source land.
But I have multiple VM's and containers running lots of Linux stuff - on Linux boxes because it just can't be beat as a Host. Even VMware is Linux-based.
Linux or ChromeOS most often. I keep one older windows 10 laptop around for specific software that won't run on anything else. I don't have to use it very often these days but when I do need it it's always for something important that can't run on any other OS.
I moved my parents to ChromeOS a couple of years ago, I use Linux on my work laptop and on my personal laptop as well.
Pop_OS for the main PC, Ubuntu for the laptop and Debian for all the servers (lots of pis). There are 2 PCs left that run windows 10, one is the media rig and the other was an AMD APU that lived in a briefcase as part of a "totally not laptop" thing I built. Its a slow process to fully migrate away from windows, but so far im managing.
Manjaro Linux. It has treated me well for two years. (Yes, I know about the controversy, I have had no problems with the distro for the last two years).
Kubuntu 24.04. When 24.10 is out I'll switch to it (usually a week or two later because I'm lazy and don't feel like rebooting). I've got two desktops and two laptops running that. Then there's the HTPC which also running Kubuntu with font scaling set real high to make it easy to read stuff from the couch (that includes Firefox with lots of GUI scaling changes; uBlock Origin makes it a fantastic anime watching station 👍).
Mine and my daughter's phones have KDE Connect so we can control the HTPC without having to get up to get the wireless mouse/keyboard 😁
The three Raspberry Pis in my house are all running the latest Raspbian image.
Debian. I distro-hopped a lot but I always return to it. It's like a kit you can turn into anything you want. As stable, bleeding edge, minimal or full-featured as you want, for all kinds of devices, with great third-party support and documentation.
Currently I run a minimal, stable Gnome system with a newer kernel from backports and Flatpaks for my apps.
The only thing it isn't good at is immutability and filesystem snapshots. Both are possible to set up, but it's an involved process, and I'd rather depend on regular backups.
I recently switched from Windows 10 to Nobara Linux and it's amazing, right now I'm playing gta 4 which only required some tinkering to work without issues. Highly recommended
Fedora Plasma Spin on my gaming rig. Wife’s laptop is MacOS. Used to run EndeavourOS, and I mostly loved it, but I trust the security and stability of Fedora a bit more after some experience with an Arch base.
Fedora on my desktop and Linux Mint Debian on my laptop.
There's been some ups and downs with Fedora, but nothing too serious at the end of the day and I do quite like it.
LMDE has been as stable as a rock and I haven't had any issues with it. I don't really use my laptop that often and its mostly just for web browsing/other simple things.
I think the path i took was something like win98, ME, 2000/NT, fedora core, Ubuntu, Arch, Manjaro, OSX/MacOS but also still using Windows on a corpo job laptop & Linux on work servers.
Windows 11 on my Surface Pro, Windows 10 on my main computer and bedroom computer (the smartest tv is a dumb tv connected to a cheap minipc), and Linux Mint on my server and old laptop.
Windows 10 or 11 on all (three) day to day systems. Linux Mint on an old laptop which is hardly ever used, and windows xp on an ancient laptop that's only used as music player, and not connected to any network.
