Hello folks, I am currently using the Logitech Cordless Trackman(or something like that), which I love. But I've been eyeing the Kensington Expert and wondering if it is worth all the hype. I've read some reviews on Amazon, and some Intel based Mac users say the included software does not work well with their computers. Is this true for you guys? I don't want to pay $90 and not have the full functionality of the mouse. Thanks!
