Review on Kensington Fusion Wireless Trackball with Orbit Technology (Model K72363WW) by Alexander Morgan

Pros: It's a massive improvement over the old wired Orbit in many ways. The shape comfortably fills my hand and eliminates the need for a palm rest. The keys are conveniently arranged, easily accessible and well pressed. The ball rolls smoothly (so far - just a day). Cons: The scroll ring steps back a few steps from my older Orbit. This one is very scratchy in sound and feel.
