I made the switch recently for probably the strangest reason.
I’ve been running win 11 for over a year using a shell tool that allowed me to move my task bar to the top of the screen and some other win 10 functionality.
However win 11 removed the ability to move the task bar and my shell program lost most of its functionality. After that I was done.
I’ve Linux off and on since 2002ish so it’s not scary to me and I’m pretty happy with Arch and KDE right now. Still the occasional crash that appears to happen sometimes when watching YouTube.
