Desktops

The good: Easy to use, on-the-fly sensitivity changer; customizable weighting system; updated design includes two thumb-side buttons; new higher sensitivity laser sensor; fully cooked Vista support.

The bad: Thin thumb buttons might be tough to use for those with large hands; electric-blue styling reminds us of a SpikeTV sports drink commercial (for some this might be a "good").

The bottom line: Logitech finally earns a CNET Editors' Choice award with this update to its flagship gaming mouse. An extra thumb button, an updated laser sensor, and more convenient and flexible customization options than the competition make this mouse easy to recommend to any PC gamer.
