Left handed user mouse discrimination eliminated (Score 1)

I'm left handed and find using a one button mouse easier than switching the mouse buttons on a two button mouse. Another advantage is for computers that have a left and right handed users. No issues when switching users. On Windows XP Home if one account is set for right hand mouse use and another is set for left hand use, login initially must be using right hand convention of left click. Also, fast user switching does not switch the hand of the mouse! Adobe Elements 2 does not work correctly with a left handed mouse. (I think it is fixed in version 3) Any other lefties have comments on this?
