I haven't used a mouse in emacs since the first week I started. In the beginning I did for the left-mark, right-copy, middle-paste. But I got over that, especially once I figured out it was an X thing. On rare occasion I might use middle-paste, but C-y is more natural ;-)

The only issue I've ever had with terminal emacs is that in some terminal emulators ^H/Delete/Backspace is borked, and you end up in the help system.
