It may be sold at a site called "Fun Shop," but we think this mouse is worth taking seriously, at least in concept. Rather than just flattening out its profile or some other flawed attempt at design, Evoluent made the "Vertical Mouse" with a far more practical ergonomic approach, as Coolest-Gadgets notes. Like the "Wow-Pen," this mouse is constructed to work with the natural movement of our hands. wrists and forearms. What a concept.
