Because tendonitis I had to change the Mouse operation from right to left. Because did not want to work so well with the traditional mouse, the trackball has been appointed. To change from right hand to the left of the TrackBack is very well suited. In this I see the strength of this acquisition.
Now after more than half a year I use the trackball for mouse and the mouse buttons to click. Very good combination.
Positives: + Independent page + Scroll wheel (awesome when used!)
Negatives: - Slightly slower than in the past with the mouse
