My grandson has a M$ one that I bought some years back.  At that time the 
design was what has been described in this thread as a marble mouse - in 
other words with a large ball on top, and two buttons by the thumb.  The 
whole thing is considerably bigger than a conventional mouse, and the hand 
seems to fit over it much better, better supported.  With the conventional 
mouse I find that I swivel on the heel of my hand to move the mouse.  I would 
say that the risk was greater there, not to mention the fact that I have a 
very sore place there on my right hand now.
