Back in 2008 NZXT released their first gaming mouse, dubbed the Avatar. Other than driver updates to accommodate newer games and provide bug fixes, NZXT has seemed content to leave it at that. You might ask then how NZXT could improve upon the Avatar's success enough to warrant a new product designation. Well you could start by replacing the 2600 DPI optical sensor with a 1600 DPI laser for better tracking on all surfaces. Then you eliminate two customizable buttons that the majority of users will probably never miss. Continue by reducing the switchable DPI selections from four down to three, throw in 16Kb of memory for storing of settings and profiles, and allow users to customize the LED lighting. Finally freshen up the aesthetics and slap an "S" model designation on it. Oh yeah, and cut the price almost in half.
