This may sounds ridiculous, but for the life of me I can't find the DPI of that thing. The moment I saw it I went to logitech's official site but other than an overview of the thing's features, nothing. Googling didn't help either. If it had 2000 dpi and on-the-fly sensitivity switches like my G7 i'll get one. Still, I'm a bit worried about the dock, I wish it had interchangeable batteries... still, shouldn't complain, that thing is badass enough already. Two wheels? I mean come on. People will say 'we don't need two wheels!'. But people also said in the 80s 'who will need more than 640k of RAM anyway?'
