FWIW I’ve got the wife happily running Debian + KDE on her (formerly win10) laptop and she absolutely loves it. I just helped her upgrade from bookworm 12 to trixie 13 and all went smoothly, solidifying her approval.

I intend to get a Fairphone 5 or 6 and test-drive Ubuntu Touch on it, hoping to daily drive it… but it’s all theoretical at this point. If I can’t get a real Linux distro to do everything I want reliably, Lineage OS is my fallback plan. I believe in the Fairphone mission, so that’ll be my next hardware purchase either way
