On which, the Cosmo or the MicroPC?

I was never brave enough to tinker with GNU/Linux on the Cosmo while it was my daily driver. I'm pretty sure that using the device that way comes with some pretty sever compromises.

On the Micro PC, I run Void Linux with KDE Plasma. I didn't do anything special, everything's mainline, so I'm sure at a technical level Ubuntu MATE would work perfectly well. The only interface tweaks I've made are to set the task manager to "icons only" to save space and added thermal/RAM/CPU monitors in the taskbar.

As for "toy gadget" vs "useful tool", I'd say that if you're the kind of person who likes to take your laptop everywhere, it's definitely for you.

Thanks. I meant on the Micro PC. I guess you already mentioned KDE Plasma somewhere. I definitely don't take my laptop everywhere, but I'm contemplating. Such a Micro PC looks very promising, exactly for the reasons you stated!

Did you try other configurations? Like i3wm? I get over 15 hours with some tweaking with a modern Ubuntu and i3wm + optimizations.

You get 15 hours of actual screen-on usage on a GPD Micro PC? Color me impressed if that's the case. Mind sharing those optimizations?
