FWIW, I've been running Linux as my primary desktop through 4 companies and 20+ years thus far. I'm not at a loss for applications, native or hosted, that I use in my day to day work.
I'm actually quite happy that I no longer need to worry about installing Microsoft office (current day job uses this suite). Online works great, and when offline, libreoffice 6+ allows me to continue to work with the same docs.
Prior to this, Google docs worked perfectly fine for $dayjob-1, and worked perfectly well across Linux, Mac, Android, so I didn't have any significant issues with it.
Really, Linux is a fine desktop. Seems to be about 2x more common accessing my blog than Mac, and about 1/2 that of windows. I can't imagine all of those are server users. Must be some polished and usable desktop apps in the mix to be able to see that.
