Eh, I dunno, I think it'll appeal to the RTS gaming crowd that dabbles in the FPS genre but not enough to warrant buying a button laden mouse for it. Now instead of buying a Logitech or M$ mouse they have the option of another big name mouse that's a bit more streamlined. Not to mention the nicety of being able to switch resolutions on the fly which some mice don't offer and lefty support.
I know many southpaws that don't mouse with their left hands due to their mice being only for right handers. This gives them another option now.
