I should have been clearer. Inferior in this case translates to "it
can't recreate my favorite environmetn, but I can recreate yours." A
two-button mouse mimicing a one-button system just treats all mouse-X
events identically - that way you can't hit the wrong button.

Studies won't change this point. Even if you proof that everyone is
always more productive with a one-button mouse, as long as there are
people who prefer a two-button system, and think they are more
productive with it, the ability to let them configure the system to
their preferences will make that system superior.
