The Orbita mouse seems to be finally coming to production. After watching that video, it seems that the mouse could be quite nice actually. We’ve seen several people build jog wheels for their computer and others try to make scrolling more ergonomic, and this product seems to add both decently. Well, it could probably be more ergonomic, but it is a start. At less than $100 it isn’t cost prohibitive either. The question is, have any of you built an alternative? Using a puck shaped device seems like it could get bothersome on the hand, how would you improve the design?
