The Sphero, from Orbotix, is one of the toy hits of CES 2011. Like the AR Drone
, the toy hit of CES 2010, you control the Sphero with your smartphone (a remote control app is available for iOS and Android). Your phone connects to the Sphero via Bluetooth, and to control the ball you can use a virtual joystick or the accelerometer (simply tilt your phone). In our brief hands on, the Sphero proved a little tough to control, but we'll chalk some of that up to the unit's dying battery. The Sphero should hit the market by the holiday season for under $100.
