The Split Personality Hela Perific Wireless Dual Mouse

The Hela Perific Wireless Dual Mouse suffers from a split personality because it can be used as a standard desktop mouse, but it also has a trackball, and it can also be used as a wireless pointing device for presentations. On top of all that, it is ergnomically designed to stare you clear of pesky hand cramps. It retails for about $120 USD, but there is also a cheaper corded version if you are strapped for cash.
