Apple has had plenty of innovations of its own when it comes to mice—some better than others—but nothing represents as much of a paradigm shift as Evoluent’s Vertical Mouse 4 for Mac ($99). Available exclusively at Apple Stores, this mouse literally turns the design most people are used to on its side.
The vertical orientation is designed to be ergonomic, moving your wrist from a twisted position to a more natural posture.
Vertical Mouse 4 connects to your Mac with Bluetooth, and is powered by AA batteries.
It has six buttons and a software interface for mapping out the controls. While it does require that you give up the Multi-Touch features of your Magic Mouse or Magic Trackpad, the design is supposedly more comfortable and should relieve wrist pain.
