Anyone working long enough at the computer using the traditional keyboard and mouse combo will inadvertently suffer from a degree of Repetitive Stress Injury (RSI) that could potentially lead to a bad case of arthritis in the later stages of life. The Wow-pen aims to eliminate that by removing the repetitive strain on your hands and wrists with its vertical mouse design. Although it looks really funny and will take quite some time to get used to, the potential health benefits could be a deal clincher. It works essentially the same way as a normal mouse with a minor relocation on the button layout. The scroll wheel has been shifted to the right side of the mouse. You can also use the Wow-pen in conjunction with the bundled Wow-electronic whiteboard software that enables the computer to directly accept handwriting. This device comes in 400/800dpi resolutions and can be connected via USB or PS/2. It is compatible with Windows 98, ME, 2000, NT 4 SP 3 and above, XP and Tablet editions.
Pros : Alleviates problems associated with RSI
Cons : Could take some getting used to, looks downright ugly
