USB Optical Mouse with Integrated Numpad

I came across this device earlier and haven't made my mind up yet on its practicality. I was thinking about binding targeting or movement of individual clones, but I could just see myself smashing down my hand onto the keys.

Measures 4.5 x 3 x 1.2 inches. $45.00 - $55.00

Its not programmable, so how is it useful? You might as well just use the numpad on a normal keyboard.

As Gurblash just pointed out to me, Its a mouse. This is now awesome.
