I like using split panes in my editor: When I'm not at my desk, I can just fit two 80 character panes in. When I'm at my desk I can fit three!

I don't follow it religiously, but I try and fit everything into 80 characters where possible (my editor has an indicator for the 80-character mark).

For me the big win with 80 is that I can easily do a side-by-side diff in my IDE without needing to expand the diff window at the expense of the outline, package, and other views. And horizontal scrolling in a diff view sucks. A lot.

Agreed, also I like to have a portrait monitor for code and browser, can see more without scrolling, so 80 helps.
