In Acme almost always I use variable width font but I still adjust column
width to 80 (for a monospaced font). That way on a full screen on MBP
I get a number of regular width columns and one narrow one which I use
to keep my to do list or to note key points. 80 columns is a compromise
that allows one to make better use of the screen real estate. I format text
or comments in narrower columns so that you can read straight down
instead of zigaziing down. Switching columns implies switching context.
Lazyness is the mother of invention!
Not sure what this has to do with "Unix as Literature"!
