Video games. I work on a company issued MBP and my own daily driver is an M1 MBP. My PC runs Windows mainly because of video games. Yes, I know about Steam's efforts and Proton, but Proton lacks DXR. I paid top dollar for a gaming video card and I want to see those rays traced! On a serious note once Linux allows me to play AAA titles with the same level of fidelity as I can on Windows, I am switching over to Ubuntu.
