I dont know how you dont like this mouse. I mean touch sensors in the freaking mouse. To right click you have to have your left most finger OFF of the mouse. I love it, it is perfect for laptop users like myself, since I am used to the clicking style. The side buttons are firm enough not to hit on accident, and the trackball is dead on precision, perfect for my photoshopping. I havent yet bought this mouse, but have used it numerous times at friends houses and at CompUSA. The only thing stopping me from purchasing this mouse is lack of funds and rumors of a wireless mighty mouse on the way.
I would much rather be wireless, hence the reason for the purchase of my macbook (hence my lack of funds).
I would just like to say, this mouse is by far the best non-gaming mouse I have used. And I also own the wireless desktop elite keyboard and mouse set released last year by microsoft.
