Exactly and some other media/creative stuff as well. Windows is the only way to run Ableton with full VST support on my own hardware. Then if I'm going to need a Windows workstation anyway, I might as well use it for gaming too, and lump in all my other "power station" uses. It's sometimes frustrating when you mention this and people who aren't familiar with these programs to try to debate you or assume you haven't entertained the alternatives. In my case I run Linux on my laptop and servers, and even some of my instruments like the monome norns and m8 are rpi based. Real time audio synthesis on linux is actually amazing, PureData and Supercollider are the ones I'm somewhat familiar with.
