My cybersecurity course uses Linux… in a VM. We boot into Windows 10, then start Kali in VMware and do everything inside of it. I still don’t know why, I just bring my own laptop with NixOS and add whichever package we are using to my shell.nix for that course.
My parents run a business, and besides having me install it and do the initial setup, they both use Linux fine and have adjusted great from their previous machines. I moved them to it mainly because of performance and being tired of fixing printers on Windows. LibreOffice runs, Firefox runs, a video editor works, and OBS runs, so it’s enough for their use. They’re both on Wayland, one on EndeavourOS (w/ a graphical app store set up ofc) and the other on Fedora Kinoite, w/ nouveau drivers and no issues so far!
