And, of course, ed is the default editor. :-) I exert geek dominance over introduction to C students by demoing using ed to modify a source file. After which I amuse myself for the remainder of the term: "Source Control? Syntax highlighting? Luxury! When I was young we had to hand-magnetize knitting needles and edit files one bit at a time directly on a Winchester drive!"

More seriously, I think the 80 column width is just too constraining with more modern languages that aren't remotely as terse as C–not to mention a limit that aggressively militates against in-line commenting. We also have monitors and fonts with resolutions that permit easily reading much denser use of the visual display. I mostly go with 120 chars now (in practice, that means that lines still won't wrap when I print source code files) and however many lines fit into the display pane.
