I rather like this list. My main everyday work machine is an Ubuntu 18 box, it's 99% awesome. Everything works, I almost never have troubles. I've been working like this for years now. I spend all day working on Linux and supporting Linux servers and other open source projects. BUT I can't get USB headphones to work. It drives me CRAZY. This is such a stupid basic thing that "just works" on every other OS but Ubuntu just fails me totally on 2 different boxes. I've tried EVERYTHING I don't want to even think about the amount of time I've waster. So yeah, reason #1 I can't abandon Windows is because USB headsets don't work on (my) Linux. This sounds like a stupid little thing, but it's a big pain for me.
