This new ergonomic mouse, called the "Wow-Pen Joy" (which Gizmodo says possesses no wow, no pen, and no joy) is set to be released in North American and Sweden next month, by Korean company WOW Technology, makers of digital pens and ergonomic mice (including a pen-type mouse, which I suppose is the origin of the name). Aesthetics aside, I can see where the shark fin shape of the mouse would be a more natural fit for the hand, as well as the upright position which doesn't force you to twist your wrist downward as with traditional mice. For $30, I'd be willing to give it a try.
