ITreviewed posted a review on the Logitech MX 1100 Cordless Laser Mouse

Big and broad, the MX 1100 Cordless Laser Mouse was designed to support your palm to your fingertips. Personally, I found it too big and heavy to be comfortable, especially compared to mice by Microsoft and Razer. At least instead of pressing down on the wheel to engage the free-spin mode, you now push a small button in front of it. Despite my obvious annoyances, digital media artists, gamers, and even power users should love the breadth of control allowed by the MX 1100's wide range of buttons. One thing is clear - if you have big hands this mouse is for you.
