WaaWoo Technology offers a very interesting new input device called the Wow-Pen.
The Wow-Pen is a cross between a mouse and a pen. You hold it like a pen, and roll it across your desk like a mouse. It provides all the functions of a conventional optical mouse, plus may also be used for drawing and writing. It includes two buttons and a scroll wheel, and is said to be helpful for users experiencing repetitive strain injuries.
The Wow-Pen is available in three versions: a desktop model (pictured) , a travel-sized model, and a deluxe wireless model. Prices range from $40 to $130.
