I used to run it, but I noticed it sucks battery like crazy.  In the
end I compromised on running X with good ol xterm on my MacBook.  It
is much more lightweight.

Plus it is impossible to create a realistic CRT experience on LCD,
especially in widescreen.  All terminals were 4:3 and rather small
from today point of view, but the sizes were just perfect for full
screen text modes.

I have tons of old terminals and CRT VGA monitors just so I can work
on a real thing.  There is something magical about the glow of
phosphor on those old tubes.
