We here at Fluke have a Scientific Calculations SCI-CARDS printed circuit
board design system that uses Megatek tubes and Summagraphics bit tablet
pointing devices. The puck (not a mouse but same function) has four!!!
buttons on it; SELECT, ZOOM IN, ZOOM OUT, and GRAB FOR PAN. The operators
spend between 10 and 20 hrs/week at the workstations. They seem to get
the hang of multi-button operation quite quickly. After about 3 months
they say they don't ever think about it any more. My conclusion is that
a multi-button mouse is a good idea for heavy use. Less complicated 
arrangements may be better for casual and demonstration use.
