I just received my PinePhone (not the pro one), and buying the SD card later today to try out this demo image (hence I posted it here as I came across it :) ). Can leave a status report once I've tried them out. Even from before trying it out, seems I'll try at least the updated images of the Majaro Phosh as I've heard it's the most stable and responsive one of the bunch, together with the Arch Linux Arm edition. Then we'll see what comes next.

The phone ships with Manjaro Plasma, and it's definitely not ready as a daily driver. Maybe it's the hardware, we'll see when I can try out the other OSes, but it's very laggy and very buggy (which to be fair, is exactly what I expect from a phone labeled "beta"), would not trust it as a daily driver.
