I think a shorter line limit is *especially* important in the age of
modern screens that are way too wide. If you were to, say, double the
line length to 160, some lines would be very long but most would
remain short. So you would lose code density (half the window would be
empty), and you would lose the ability to have more windows
side-by-side. Also, it so happens that 2 80-char windows fit
*perfectly* side-by-side on a rotated 24" monitor (1200x1920).
