Buffalo is introducing a new mouse that offers a D-pad to replace the typical scroll wheel button. The Buffalo BOMU-JK/M has a D-Pad button that allows for scrolling vertically and horizontally, the same D-Pad buttons found on the Playstation and XBOX 360 controllers. This allows for better control for scrolling but scrolling lengthy pages might be slow compared to a scroll wheel. Only available in Japan for 3,320 Yen ($28). Source and Product Page (Japanese)
