It looks like Wolf King is trying to start a trend with their odd brand of circular gaming keyboards (check out previous reviews here, and here). I'm not so sure if it will catch on, but it has that strange, novel, appeal that keeps me coming back for more.
The Bongo like design looks relatively functional, but it would take someone truly dedicated to bizarre technology and design to get used to it. Wolf King typically designs with gaming in mind, and I can see how this would a more ergonomic setup for a hardcore gamer.
