You can also use it to run things like a daemon. For instance rtorrent does not have a daemon mode because you can use screen or tmux to "hide" it by running it in tmux and then detaching. You can then re-attach to the processes to interact with them later. You could probably do this with tags in a tiling WM. I like to do this with rtorrent and pianobar (command line www.pandora.com client).
