Microsoft's Arc Keyboard was already quite an eye-catcher in its original black, but we may just have to give the edge to this new white version with lime green accents, which is now exclusively available for pre-order from Amazon. Of course, the color is the only thing that's changed here, with the keyboard still sporting the same slim, arched design, the same tiny 2.4GHz USB transmitter and, unfortunately, the same $59.95 price tag. Still no exact release date just yet, but the keyboard will apparently start shipping out sometime in June.
