Contour Design is a company that specializes ergonomic alternative computer input devices. We’ve reviewed a couple of their products in the past (see related articles list at the bottom of this post) and their latest product is the RollerMouse Pro2. This device replaces your mouse with a keyboard wrist rest that has a built in cursor roller bar that spins both up and down and from side to side simultaneously to navigate the cursor over the entire screen. The RollerMouse Pro2 can also lift your keyboard to a desired angle for more comfortable typing. This product looks like an interesting alternative to a roller ball, but the price will probably scare away a lot of people at $199.95.
