About 18 months ago i pulled them back out and ran XFCE on one of them. It crashed with the X11 error (i kid you not): "event arrived before it was sent (your hardware is too slow!)" (going from memory - it might have been phrased differently). i ended up giving them away to someone who wanted to use one for a pihole server, and i was glad to be rid of them. Utter garbage, they were.
You misunderstand. i didn't back the phone/laptop. i backed the first pine64 boards, which were marketed as being much more capable than they turned out to be:

Right now it runs some services through Docker and is pretty dang solid.
I've never taken any manufacturer's performance claims too seriously, there's always an angle.
