Kensington Expert Mouse = optical trackball (you didn't provide separate tickyboxes for wheeled and optical, tsk) + scroll ring (which I equated with a scroll wheel) + four buttons. In fact I use all four, and the scroll ring, on a regular basis; this is an Ubuntu box, and firefox by default maps #4 to the back button.
