Dang dude, you totally one-upped my mouse. I got the Razer Diamonback, which only had 4 programmable buttons (beyond the normal buttons) and I really only use the two my thumb can reach. It has two on the opposite side, but I hate using my pinky for anything other than letting people know how pretentious I am, when drinking tea.
Let me know how that thing pans out, because this Diamondback is about 4 years old and that's like 80 years old in people years, and I may want an update some time
I ain't really diggin' the Razer/Belkin/Nostromo n52te thingamajig, so much. Gonna keep it though since my software is changing a bit and I might find uses.
I -love- the Razer programmable mouse macro recorder thing, though. Super easy to use, imo.
