I'm a bit of a trackball fan. out of the ones in this poll, I have the Slimblade, the Expert, the M570 and the Orbit, (except I have the Orbit with the scroll ring). I'm curious enough to try out the CST. Out of the bunch that I have, the Slimblade is my favorite. The M570 also sees a lot of action, as I use it for my HTPC.
thebaronSlimblade looks awesome. However, I don't think I would get much use out of the Media and Document modes. Is there a way to re-purpose the upper two buttons?
