I use it all the time when doing stuff on the server(s). Log in with ssh, start tmux, and then do whatever. If the ssh session dies, when I reconnect I can keep going. You can leave tasks going (say a long find command, or sorting out log files, or du or whatever, so that you can come back later and keep going. In terms of use, it's pretty similar to a tiling wm, just in the terminal, that works over ssh as a session, that you can share between people, or screens. So you can open the same set of windows on multiple computers simultaniously. Say have a raspberry pi with an el cheapo monitor up above your desk, monitoring something, then log in with your workstation, do stuff, and leave it going, still being monitored on the pi the whole time. Session sharing with colleagues works well as well.
