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.
Once I was looking forward to the challenge of connecting a linux PC to a Windows domain, only to find out the current version of the distro had that functionality by default. 😐
So that was cool, I guess…
