Who would actually want a mouse with this many buttons on it? This thing has all the controls you would expect to find on a media keyboard, but jammed onto a mouse for some reason. Personally, I don't find the notion of a mouse of this type appealing. To add Insult to injury, the "mouse" moves the only two buttons you really need on a mouse, the right and left click buttons, to the front conveniently located (NOT!) under the USB cable. That has to be the most ergonomic design I have ever seen. If that is you live in bizzaro world.
