Thanks, I've never heard of ArcaOS, AROS or MorphOS before. Always nice to find new things.

I don't daily drive them as they don't really seems like daily drivers. I'd be surprised if even the devs manage that. Temple OS is really only useful if you want to align with the divine, Plan9 could be doable if all you do is code and appreciate acme but even then it's a research OS that's meant to be deployed on a network, everything is a file!, but seems to mainly target just running as a vm.

I tend to play around with linux and bsd, occasionally even hurd, as they seem to have better potential for getting basic 'daily driver' functionality even in obscure niches.

The Glaucus dev has an nice https://github.com/firasuke/awesome of projects that inspired them to create a beautiful little daily driver linux OS. I tested Glaucus a few years ago but my current systems are ancient and Glaucus is targeting new tech, which is nice.
