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.
You could see it as time invested. For me, it’s something I do in my free time, on an old laptop, for the fun of it. And for the learning aspect of it.
My main system also runs Linux, but I don’t tamper much with it. It just runs. Reliable, predictable, boring. Boring is good for important systems. But that’s not why I run Linux.
I will invest my time elsewhere. Boring is good, Debian Stable all the way.
