Actually I'd have to disagree ... just because we've used pens for so long doesn't mean its necessarily the right way of using your muscles (notice all those pens out there that are designed to help muscle cramps for instance). Besides which using a Windows PC requires at least 4 input signals, (pointer move, pointer drag, pointer action, pointer secondary action), at least 3 for a Mac and at least 5 for an X interface. A pen by itself can really only provide one (hence why the Palmax has buttons on the rear left of the panel and other tablet-pen type devices have buttons on the pen itself, a situation that isn't really terrifically ergonomic as the forefinger is the only one that can really press buttons in a pen situation and that affects accuracy). In my opinion, the best pointers are well designed, lightweight mice followed by trackballs in their variety of incarnations ... trackballs provide the tactile feedback of pens or trackpads, the support, stability and inertia of mice, a choice of which muscles to use (thumb, first finger, second finger, multiple fingers) and the ability to naturally provide access to a variety of pointer inputs. Of course, there are a number of really poorly designed trackballs and a number of pretty well designed ones which can be a problem ... I do think that the trackball on the screenside (as was used in many laptops in the mid 90's) was superior to the eraser point ... you didn't need to put force on it to get it to move fast for instance. Cleaning is the only problem ... - Raymond P.S. FWIW, I use an accupoint on one laptop, MouseKeys on another, a mouse to play games on my PC and a Logitech TrackMan FX trackball for general tasks on my desktop. --- /~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\ | | "Does fuzzy logic tickle?" | | ___ | "My HDD has no reverse.
