I stick to 132 character lines and display two files next to each other at the same time. If I stuck to 80 character lines, I could have three files on screen at the same time. There's a limit to how wide code can be while remaining readable, even though it can be wider than prose: I struggle to read prose that word wraps at 132 columns, and I expect I'd struggle to read code that used 200 columns.
