It’s more of a “why do I keep Windows on my main machine and only use Linux for my servers?”
The answer is two-fold
a) most of my games and a (dwindling) amount of productivity software are windows based. I know things are improving… But the fact remains that I am still literally invested in some software that is only supported on Windows (that pile is shrinking).
b) there are a few everyday tasks that are still just too frustrating to be practical for non-technical people. For example, why in the fuck do I need to deal with user and mod permissions for files on an external harddrive? I get why for system files, but for media files on an external drive? It’s a level of pedantry I’m just not ready to deal with.
