Personally I haven’t. While Linux is imperfect, choosing the right distro makes the rest of the experience straightforward. And with it’s whole complexity, I find Linux more user friendly than Windows. Even driver issues, broken shadow file ownership and KDE specifics only made me more confident about my choice to use Linux after I solved everything.
Just gaming on Linux Mint. Most big modern games work, but support for older and smaller games just isn’t there. I tried to play Doom 3. It wouldn’t start. Shadowrun Hong Kong was so slow it was unplayable.
