 surface of the mouse, as well as scrolling both vertically and
 horizontally with the tiny trackball, you can also left-click,
 right-click and squeeze it & it detects all separately.
 I don't like it - I prefer more obvious, tactile buttons; it used to
 amuse me to use a MICROS~1 mouse on my Mac - but the Mighty Mouse
 /did/ support 3 or 4 button actions. The Magic Mouse, while much
 simpler, doesn't - but its multitouch surface does allow gestures to
 perform most of these actions. 
The Magic Mouse works exactly the same as the Mighty Mouse when it
comes to clicking: there's a single switch for detecting the clicking
motion, then there's a capacitive surface that detects where your
fingers are on the mouse surface and interprets the click as a left or
right click, accordingly.
