Kensington donned its thinking cap to come up with the Kensington StudioMouse Wireless. The conventional scroll wheel is replaced by a flat sensor; slide your finger forward on the sensor to scroll up and backward to scroll down. Without a wheel, you don't have as much tactile feedback, but the mouse makes up for that with fully customizable drivers. These allow for scroll-speed adjustments, application and Internet shortcuts, and even rest reminders.

With a thin, flat chassis, the StudioMouse feels comfortable in the palm. The design looks more Mac than PC, which makes sense since the built-in graphics shortcuts for Adobe Photoshop and Illustrator work only on Macs. Mouse pointer movement is very smooth, with 800-dpi optical-sensor DiamondEye technology. But the StudioMouse lacks the high-powered reach of its Bluetooth competitors, with only a 6-foot range.
