Got my powermate today. Didn't have too much time to mess with it, but it seems pretty cool. It's a USB knob, which you can set up to control any app with a side-to-side mouse motion. I will give a more detailed review when I get some time to put it through it's paces. It is quite heavy, and the blue light is very bright. Nice "Cool" thing to add the desktop to make people jealous.
