Never figured out why companies design mice with a longer left click button, it's completely opposite to the shape of your hand.

Another adns 9800 sensor no thanks, enough of them.

I wish corsair or logitech would design some kind of mouse very similar to mx518, I know there is this mx400s and Iam using it right now, but it only has the optical sensor...I always wanted to try out some of the mice with laser or if microsoft made another cool looking version of the old IE4.0 with the bluetrack technology. Damn I would buy one of those for sure !
