I've been a GNU Screen user for a good while. The increased productivity is wonderful. However, I'm prevented from switching to Tmux because you can't attach to the same session from multiple terminals, and show a different window in each terminal. I use this all the time in Screen - in Tmux, changing the window being viewed in one terminal, changes all other terminals attached to that session.
