    Yes!  The mouse on the Blit (Commercial Version -> Teletype DMD 5620)
was also dome shaped, with the mour buttons located on side rather than
top (near the tail).  It fit nicely into the palm of my hand.  However, for
people with long fingers, it may not have been so comfortable.


     I find that most often I grasp the mouse (on a Sun 3/60) on the sides
with my thumb and the pinky *and* ring finger.  The reason for this is that
by only using the pinky on one side, I feel fatigue in that finger very
quickly.  However, this means that one of the fingers used to depress a
mouse button, assuming a three button mouse, must server two purposes:
to help the pinky and then depress one of the mouse buttons.  Otherwise,
one must use the middle finger to cover two mouse buttons.
