Here is my set up: I run emacs in server mode doing most of my work w/ an X11 emacs client, and eshell when I need a Unix prompt. As much as I like eshell there are many scenarios where I prefer zsh so I run zsh in tmux and invoke a non-X11 emacs (-nw) client within tmux to go back and forth (copy/paste whatnot) between emacs and zsh. Repetitive strain problems aside, I am generally pretty happy with this setup.
