Getting a bit of a downvoting there, @datavoid. I'm a Linux dev that works for a Linux shop that runs Linux on all his machines at home; I personally love the fact that I can send my test team and any customers having problems a list of shell commands to fix it all. (Quite a lot of our customers are more adept than I am, will send me back an improved version.) Much easier than a list of which buttons you have to push and a hundred screenshots, much more flexible when you've dozens of remote servers to deal with. But yeah, if you expect a GUI all the time, it takes a mindset change.

Linux has made enormous improvements in game compatibility recently, to the point that I don't much bother checking ProtonDB any more for most things I'm interested in buying off Steam. But there's still problem areas - funky DRM, very specific performance requirements, and reasonably small target audience - where some games just don't work right, and that's basically the problem checklist for most high-end audio stuff as well. Can probably add a driver requirement for specialist kit, too. Might be a struggle to fix that; requires manufacturer support, and they've not much interest in supporting a small market.
