There’s no doubt that Logitech has become the household name in human interface devices like mice and keyboards, however we’re impressed by the ways in which the company continues to push the envelope with new design ideas. Last year’s MX Ergo trackball, for instance, brought back the classic trackball in a really great ergonomic design, and now the company seems to be following up that idea with MX Vertical, a new “Advanced Ergonomic Mouse” that borrows some of the same ideas to provide what may be the most uniquely designed mouse we’ve ever seen.
