Good idea, but... [Posted on 2008-08-26]
This product is a step in the right direction for reducing hand/arm motion - you can use it to point and click without leaving the keyboard. But - the mechanical trackball dpi is too low - it requires too much effort by your thumb(s) to get around. A touchpad is better, but sometimes they're too twitchy.
