I use windows maybe once a year to see if some software builds or maybe play a game for a bit. It's almost comical how bad the experience is every time. Your comment on mental fatigue nails it - nothing on its own is _that_ bad but it all adds up and elevates the baseline stress level when you just want to get some stuff done.

My oldest son switched to Linux last week, but already wants to switch back because of gaming performance. But he found something called Tiny10, which is apparently Windows without all the bloatware. That might be a solution for people who really don't want to switch to Linux. But I'm never going back to Windows.
