Max: I have used a TrackMan Marble for about two years. As I do a lot of CAD
my hand is on the trackball for hours at a time. The thumb is actually about
an inch BELOW the palm. It is the most comfortable pointing device I have
ever used and is a very natural hand position.

* There is some thing I find interesting. Most of the high-tech,
* expensive and stylish mice [Logitech for example] place your thumb
* on the side of the mouse, almost touching the mouse pad. The
* trackballs, as far as I understand, are operated by thumb and in
* this way a hand assumes an opposite position from utilized by mice
* (standard mice are about midway between these extremities), this is
* - with thumb up relatively from the hand surface. While I observe
* my hand movements, I see that my thumb is usually lower than a
* palm surface, so the logical conclusion would be that trackballs
* place hand in an innatural position.
