The Logitech MX1100 Cordless Laser Mouse

The Logitech MX1100 Cordless Laser Mouse, the newest addition to the MX line of performance mice, is bulky, heavy (5.55 ounces with two AA batteries)—and comfortable. Although tailored to general-purpose computing, it's versatile enough for gaming. Rubber-like material on both sides assures a good grip, and the large, contoured body lets you rest your hand and move your wrist or use your fingertips for more precise control. The shape, however, suits righties more than lefties.

Combining the highly customizable mouse with the best-in-class SetPoint software (included), lets you set vertical scrolling to be clicky and line-by-line or hyperspeed (sideways pressure causes horizontal movement), switch dpi settings on the fly, and remap eight of ten buttons under Mac OS X 10.3.9 or later, Windows XP, and Vista. The 2.4-GHz wireless provides a strong, reliable connection, even in busy wireless environments. 

The laser sensor allows settings from 400dpi to 1,600. While $79.99 is hefty for a mouse that's not gaming-specific, the comfort and solid performance even over non-smooth surfaces justifies the price.
