Rev-up your notebook with the new VX Revolution. Logitech´s innovative MicroGear Precision Scroll Wheel lets you fly through long documents at hyperspeed, or switch to precise click-to-click scrolling to navigate lists, slides, and image collections. Search the Web by highlighting a word or phrase and pressing the Search button. Effortlessly zoom in and out of photos, spreadsheets, and documents with the convenient zoom slider.

Personally I prefer Bluetooth, no dongle to mess with, but if your looking for a cool mouse that, does just about everything, your search is over.

There is a pretty in-depth review of this device that the folks from Hardware Secrets put out. The review is available here
