| The Bottom Line | The 3M EM500 Ergonomic Mouse requires some adaptation, and it offers only the most basic mouse functionality. But the payoff is a more comfortable mousing experience. | Evoluent's updated VerticalMouse 3 refines its longtime ergonomic mouse product into a robust modern competitor. It lacks the wireless freedom of Microsoft's recent ergo mouse, but otherwise, it's just as comfortable, more feature-packed, and better designed. Just don't be afraid of its unorthodox looks. | Logitech has met and surpassed Microsoft's recent mouse technology innovations by introducing the most versatile mouse sensor on the market in its new Performance Mouse MX. But even if you don't have a glass table crying out to become a workspace, this high-end input device has enough features and cushy design to make it a justifiable indulgence for anyone who takes their cursor control seriously. | Aimed at relieving or preventing the onset of repetitive stress injuries, Microsoft's new mouse seems to have the right idea in its redesign of the standard mouse grip. If Microsoft's hardware design team had paid as much attention to some of its other elements, this mouse would be a winner. | |
