>< g >One very cool feature on this is forward and back buttons that used with the browser. There's one on each side. No more moving the mouse up to the toolbar.

Once I got used to the forward and back buttons on the side of my optical mouse here at the office, I really liked them and using them became a natural habit. The mouse on my home computer lacks these buttons, so now when I'm working at home I'm always pressing on the left side of the mouse out of habit and then momentarily wondering why nothing happens. D'oh!
