I'm also wondering about this. I've been using screen for almost 20 years, and wonder if there's a compelling reason to switch.

Take a look here: http://unix.stackexchange.com/questions/549/tmux-vs-gnu-scre...

Some of it is arguable, but for me one of the greatest benefits is how tmux will auto-resize to the smallest terminal connected, making it useful for screen sharing or when connecting to an existing session from a mobile device.
