I like the idea of being able to control the mouse pointer whithout having to stretch my arm to reach the mouse on my desktop. I have a T300 and there's a very nice place on the front left of the base where I could stick or screw a trackpoint or a small touch pad or trackball. The mouse buttons would be the buttons on the right of the base, remapped via script. Any idea if any of these exist as independent usb devices? Any other alternative?
