As a wrist and shoulder rsi victim, I found after trying a dozen of "especially designed" and priced accordingly devices that this is the most conveniant and relieves more muscles than any other i've tried. Wheelmouses should be banned anyway, those are great for home use. Do not try to scroll trough your daily portion of screeninfo please.. !
Also and in combination with the marble i make a lot of use of my Spaceball-5000 and not only in 3d designing, most apps support at least the scroll and zoomfunctions which are usually more stressing than the other mousefunctions..
