i have never used a wireless mouse, so bear with me if this seems like and absurdly obvious question. i am planning on buying a PB when/if a new update ever appears. would like to do some moderate gaming (FPS, online) as well as real work. for real work, i want a wireless mouse. will it suffice for gaming as well? disregarding, for the moment, the issues of 2 buttons and a scroll wheel, do you get constant, speedy and accurate enough feedback from the wireless mouse to play a first person shooter effectively? thanks for your help.
