I did use one for graphic work until the batteries leaked in the pen which has now rendered it useless. It was a $60 cheapie from Aldi but gee it worked really well up until the leakage. I have a lot of trouble with arthritis in my hands and I found it to be a lot easier and with less painful consequences than a mouse. Overuse of the mouse has also resulted in some painful and debilitating muscle problems - I have had to restrict my computer usage because of it. My physiotherapist told me that it is starting to be a very common problem amongst the work force.
