I have used a logitech marble thumb-ball mouse for 3 years and it really is the dog's. No wrist strain and 3 user configurable buttons. They may do a wireless model now and you have just reminded me to look them up as I have just bought a 15" 1.5GHZ powerbook and it really is fantastic. Hope my earlier drivelling helped.
