I’ve had a framework for 2 years now. It’s run fedora, manjaro (arch based) and Debian with no major issues. Manjaro had some problems with KDE and the high DPI screen. Sometimes the scaling was inconsistent between apps. Fedora just works.
Only hardware issue is the battery life is just not that great. And the trackpad doesn’t always work property, but I think that was a first generation issue that’s been resolved since.
