I just picked up a Logitech MX Revolution mouse and I must say it’s a great mouse. It’s a wireless mouse using RF. The USB receiver is small and it comes with a cradle that recharges the mouse. The shape is nice and my hand feels great when using it. There are a lot of buttons that can be customized to open different programs or websites. What’s really impressive is the scroller. There are 2 modes – hyperfast and traditional. The hyperfast scrolling allows you to “flick” up and down. This is beneficial when viewing tall and long documents and/or web pages. You can toggle between the 2 modes by clicking down on the scroller. Here’s a pic that compares the size and contour of the MX Revolution, MX 310, MX 1000, and a Rocketfish bluetooth mouse.
