I'm not going to dump my standard mouse for this, but it's nice for sufferers of carpal-tunnel syndrome. This is a pen-shaped mouse with scroll wheel and two buttons on the front. It was actually very responsive. Although I wasn't able to sign my name with any fidelity, I was able to make curves and circles, which are pretty difficult using a standard mouse. Artists take note?
