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.
Before Proton, I wasn’t able to consider Linux as a viable solution for home computing at all. I could set up and manage a pihole, and salvage an old laptop to use for word processing and email, but couldn’t run anything my family or non-techie friends were familiar with.
Sure Wine was a thing, but I think for most casual users it wasn’t worth the hassle.
My first attempt with Ubuntu 15ish years ago was horrible; almost nothing worked, GPU support was trash, it was just an all around miserable experience.
With proton, stuff just works. It’s like a whole new ecosystem now.
