Tired of the stupid scroll wheel on your mouse? Honestly, I love mine, and don't really see any room for improvement. Buffalo thinks that they may have designed a better alternative to the scrollwheel.
Yes, it's a traditional D-Pad like you would see on most game controllers. What's it doing on the mouse? I don't really know. You can't turn it sideways and use it as a game controller. It serves the same functions as my scroll wheel does. (Yes, my scroll wheel goes side-to-side)
There aren't any other features to see here. Just a plain optical mouse with an identity crisis. I don't see any reason to pursue this item unless you're really unhappy with the performance of your scroll wheel.
