I wanted to share with others the benefit of finding a mouse alternative that may be a better shape, size, etc that may suit your needs. For me, I wanted a pointing device that was small and had easy to push buttons. This device is really a special joystick – it’s just that the “joystick” is actually a stubby little thing that your thumb fits nicely on as if it were a trackball. It is a nice flat shape that suite my hands well and allows for normal 2 button mouse tasks. It was originally designed to be used for presentations, etc, but it works great as a normal mouse. See the pictures to get an idea.
