SteelSeries drops WoW-oriented 15-button mouse, yes 15 buttons
When I was talking to SteelSeries about this beast, they insisted that this wasn’t part of an “arms race.” No, because in a battle of ergonomics, doubling the buttons isn’t always a good idea. But they assured me that they have been working really carefully on this thing to make it usable in the first place, and actually useful in the second. I’m thinking that the diamond-shaped button goes four ways and there’s another on the far side, which, added to all the other buttons there, makes 15.
