Microsoft Kinect! Yes, it's Microsoft Kinect that is claiming the title of "World's Fastest Selling Consumer Electronics Device" according to Guinness World Records. Did you guess the iPhone 4, which was sold three million times in the first three weeks of launch? Perhaps you chose the iPad, which was sold one million times in 28 days. Both are wrong!

Microsoft sold more than eight million Kinect units within the first 60 days on the market -- 133,333 per day. Kinect is a gaming add-on for the Xbox 360 with built in webcams used to track your body movements in order to control the game. It's an entirely new and interactive way to play video games.
