I've been thinking about testing that myself. There's a few things that are just a little more intuitive for me on Windows versus Linux, and for the handful of games that prefer Windows configuration or makes it easier to game on Windows might be handy to have a way to access Windows without it being my daily driver.
Then again, I have multiple computers and I already run Linux on my laptop which is the primary device that I use, I'm just talking about my game / audio workstation.
