I'm actually currently installing Ubuntu 18.04 on one of these A6A
BBBs, it seems to be going OK after a slight hiccough due to just one
corrupt executable.
It seems that one can even run Ubuntu's "do-release-upgrade" to move
to newer releases, I'm trying this at this very moment on the BBB
where I have Ubuntu 18.04 installed. I have a fast[ish] internet
connection here at home so it's not too slow.

OK, so it's down to the quality/speed of the microSD really. Given
that and the fact that speed doesn't really matter all that much for
the things I'm using the BBB for I may as well stick with running from
the SD card.
Thanks for the (as always useful) replies Robert.
