The problem is that on regular 13/14" laptop screens, it becomes hard to have two code editors side by side if you make the lines too wide.

And that's before we factor in all the nonsense IDEs like to clutter the screen with.

I would probably be better off setting up a tiling window manager etc. to have two terminal windows side by side (I've really never liked conventional IDEs), but old habits die hard. In my youth I would just dump a handful of small text editor windows on the screen in random locations, one per currently relevant source code file, and nowadays I still have to fight that urge. (Discovering that gnome-terminal supports tabs definitely helped, though.)
