I must say, these days Thanko is cranking useful products. In the last week, we saw USB Cooler Mouse, and today its time for its playmate -- the USB Cooler Keyboard. Just like the Cooler Mouse, the Cooler Keyboard comes with in-built fans to keep your palms from being sweaty. The Cooler Keyboard uses same technology as Cooler Mouse, but the only difference is that the keyboard features three fans (instead of one in Cooler Mouse) to keep sweats off your palm. It is now available in the Japanese market for about $65.
