RE:
"magic mouse has multi touch and gestures"
I don't use gestures at all.
In fact, on my MacBook Pro, one of the first things I did was disable EVERY "Gesture" the trackpad was capable of producing.
All I want is left click, right click, and scrolling (not "natural" scrolling, either -- I want the "old-fashioned" kind!).
Anything more than that is too confusin' for this old guy and often produces completely undesired results!
