I also use Windows... for gaming once a week, because it provides a passable experience using my crap PC hardware. I use a mac for everything else because it lets me get work done without being distracted by how poorly text is rendered, how dated some of the icons and interfaces are, or by the fear that I'll need to re-install the operating system once in a while. For me, my Windows pc is my Chromebook with a gpu, for others, it's their primary.
