However, despite really, really wanting to switch (and having it installed on my laptop), I keep finding things that don't quite work right that are preventing me from switching some of my machines. My living room PC, which is what my TV is connected to, the DVR software that runs my TV tuner card doesn't quite work right (despite having a native linux installer), and I couldn't get channels to come through as clearly and as easily. I spent a couple of hours of troubleshooting and gave up.
My work PC needs to have the Dropbox app (which has a linux installer), but it also needs the "online-only" functionality so that I can see and browse the entire (very large) dropbox directory without needing to have it all stored locally. This has been a feature that has been being requested on the linux version of the app for years, and dropbox appears unlikely to add it anytime soon.
Both of these are pretty niche issues that I don't expect to affect the vast majority of users (and the dropbox one in particular shouldn't be an issue at all if my org didn't insist on using dropbox in a way that it is very much not intended to be used, and for which better solutions exist, but I have given up on that fight a long time ago), and like I said, I've had linux on my laptop for a couple of years so far without any issue, and I love it.
I am curious how many "edge cases" like mine exist out there though. Maybe there exists some such edge case for a lot of people even while almost no one has the same edge case issue.
