@ai6yr I've seen a few professionals still use Windows XP/7 although not connected to the web, just to do their job. They know keyboard shortcuts of the programs they use, they work real damn fast with it, and most importantly it's what works for them.
Preferably I wish they'd try out a Linux distro and see if they can replicate their workflow there but yeah. I follow the rule of "don't fix what ain't broke."
