I'm also biased, but I've been making illustrations for my company's blog posts. Doing these in between other work. :) https://blog.conjur.org/

I've been a Mac guy fooooorever, but have used PC on & off at different jobs. My current gig is PC based, so my work machine is on Windows, but even at home I just made the switch to a PC. Being able to customize exactly what I want at a fraction of the cost was huge.... another huge point was gaming.... made the move from console to PC. Gaming on a Mac just aint happening, It does drive me nuts I cant use Sketch or XD on Windows yet, but those are just tools, tools that will eventually get to PC (dunno about Sketch, but XD will be)
