Same here. I like nano because it's a simple and intuitive editor that doesn't do much (though it does have some surprisingly powerful features once you know the shortcuts). I already have a full-blown IDE running on another screen and I don't want to spend any energy trying to stay on top of another one.

In other words, I would not use nano as my primary editor, but it's perfect as a secondary. If I need to edit more than a few lines, I'll just load up the file on my usual IDE.
