Microsoft Wireless Laser Mouse 7000 (2008)
The Microsoft Wireless Laser Mouse 7000 isn't cheap, but if you want to go wireless and have an extra $70 lying around, this mouse is certainly an option. If you're going to spend that much, though, we think you'll like Logitech's high-end offering better.

Microsoft Wireless Laser Mouse 6000 (2008)
The Microsoft Wireless Laser Mouse 6000 is travel-friendly and more comfortable than your standard point-and-click, once you get used to a few design quirks. If you're looking for an accurate wireless mouse and don't mind replacing batteries once a year, then the Microsoft Wireless Mouse 6000 is the way to go.

Trust GM-6400 Gamer Pack Advanced
The Trust Gamer Pack Advanced GM-6400 gaming-mouse-and-headset-combo is not a bad way to sell hardware to gamers, but we had some sound quality issues with the headset. Those problems and the high price tag scared us off.

Logitech G9 Laser Mouse
Usually we're fans of Logitech's gaming mice, but its highest-end G9 Laser Mouse is expensive, overly complex, and lacks the ergonomic thought we've come to expect. If you like to brag about dot-per-inch limits, perhaps the G9's 3,200dpi laser will be enough to sell you, but for the price, we expect the design to match.
Specs: External, PC, USB, 3200 dpi, 4 pin USB Type A, Mouse, Wired, Laser

Microsoft Sidewinder Gaming Mouse
Microsoft took almost every popular feature of various high-end gaming mice and wrapped it into one highly customizable product. The design could use a little refinement, but otherwise the new Sidewinder Gaming Mouse would be a worthy addition to your PC gaming arsenal.

Microsoft Mobile Memory Mouse 8000
Microsoft's ambitious, if slightly awkward, Mobile Memory Mouse 8000 covers all the bases with built-in memory, both Bluetooth and 2.4GHz, and even a rechargeable battery.

Microsoft Bluetooth Notebook Mouse 5000
For mobile mousing without the hassle of a receiver, Microsoft's Bluetooth Notebook Mouse 5000 fits the bill as long as you don't mind its somewhat lumpy design.
Specs: External, PC, Mac, AA type, Network, 1000 dpi, Mouse, Wireless, Laser, Gray

Microsoft Wireless Notebook Laser Mouse 7000
A little bit bigger and the Microsoft Wireless Notebook Laser Mouse 7000 could be a regular desktop mouse, which makes it easy to use, but not the best for easy traveling.

Logitech VX Nano Cordless Laser Mouse
If you can afford its high price, you'll be pleased by the Logitech VX Nano Cordless Laser Mouse's comfort, features, and extremely portable design.

Kensington Ci70LE Wireless Optical Mouse (rouge)
The Ci70 LE Wireless Optical Mouse straddles the line between a laptop mouse and a traditional desktop mouse, but this hybrid represents a compromise on both fronts.
