I switched my primary desktop to Debian XFCE a year ago. Took me a while to "distro shop" and install NVIDIA drivers and set my keyboard shortcuts, but now that everything works it keeps chugging along with no drama. I turn my PC on, start streaming music, and hack on my little side project code. Lovely.

Most non-gamers probably only need a web browser, so I think a lot of people could get away with this (maybe with a distro that pre-installs drivers they need).
