GeekExtreme have the yet-unreleased Razer Viper, and optical mouse designed with the gamer in mind. Can an optical mouse unseat the company's own Boomslang line? My first impression of the Viper was that it's a bit small. Of course, I have large hands, so when I think a mouse is a bit small I try to remember that everyone out there does not have big hands. That being said, the Viper has rubberized "grips" on the side of it, that aside from lighting up and looking pretty when you move the mouse, make it much easier for a person of any size hands to use this mouse while still maintaining comfort. Once you teach yourself a proper grip, there's little to dislike about this mouse, even with its smallish size.
