Title: remember mice are vermin!
Review: The computer mouse might have been designed to create stress and pain for wrists and fingers. The trackball is a great alternative. I use this one with a windows 7 64 bit setup. The included mouse software works well and allows for pointer movement settings different than those of the trackpad built into the desktop replacement laptop I use it on. The scroll ring does make a bit of noise when you use it, so not perfectly perfect, but worth it to dump the mechanical rodent!
