Stocks to Watch:
The Xbox Kinect quickly became one of the hottest gadgets of last year's Holiday season. And with good reason. For the first time, there was no need to use a controller to play video games. As Microsoft's marketing slogan goes, you are the controller. Now Kinect not only supports motion input, but voice input too. Why it's innovative: Kinect is just the beginning. Imagine Kinect-like technology coming standard with your TV or gaming consoles. It'll make in-home entertainment much more immersive. The remote control is dead.
