Evoluent VerticalMouse 2 is a vertical mouse
The Evoluent VerticalMouse 2 keeps your hand in a vertical handshake position which the company claims is more comfortable than current mouse positions. I gotta admit I'm a little curious, though I can't imagine you'd have as much control with the side of your hand as you would with your palm. Though I've been wrong before. Like the time I mistook my TV for my microwave. Boy, that was a messy day.
