[chbot] Playing with a Pi 400.

[Richard Jones]

The 8GB RAM version came out after I put my setup together. I run the Rpi4
with graphical cpu, memory and temperature indicators constantly displaying
on the top bar. I hardly ever run into needing swap, but have it enabled to
avoid lockups. For a general purpose desktop using ARM 8GB RAM does not
seem to be as important as it is with x86. If I had to buy a replacement I
would buy at least 4GB.

YMMV
