Smartfish has finally released its opus into the world: the Engage keyboard. It's been known as the Pro:Motion and ErgoMotion over the years, but now it's got a new moniker, a classy all-black look, and a $150 pricetag. Outside of the tilted design and large palm rests, the keyboard has an internal motor that moves the position of the two halves of the keyboard based on your typing frequency. The periodic position adjustments help fight off fatigue, an approach developed in conjunction with The Hospital for Special Surgery in New York City. We'll try to play around with the keyboard at CES -- last year's prototype wasn't terribly impressive -- but if it's anything as good as the Smartfish Whirl Mini Notebook Laser Mouse, we might have a new carpal tunnel warrior in our arsenal.
