Apple may have to eat crow, if Guinness World Records has anything to say about it.

[ad#Google Adsense 300×250 in story]Guinness has dubbed Microsoft’s Kinect the fastest-selling consumer electronics device on record, according to a report published by the BBC. The Kinect is a sensor bar that attaches to the Xbox 360 video game console, enabling users to interact with video games by waving their arms and hands rather than having to hold a controller.

According to Guinness, Microsoft sold eight million Kinects in the first 60 days of availability, and has sold more than 10 million since the product hit store shelves last November.

Apple sold about 15 million iPads from the time they first went on sale in April, 2010 through Apple’s most recently-reported financial quarter, which ended in December, 2010.

Apple’s iPad briefly held the “fastest selling consumer device” honor (appointed by analysts, not Guinness World Records), when the iPad’s adoption rate was compared to DVD players. That success has been repeated by Apple in its marketing of the iPad, most recently in the “iPad Year Zero” promotional video posted by Apple following the iPad 2’s introduction in San Francisco last week.

The Kinect’s success notwithstanding, the iPad has been a monster hit by any measure, and has far exceeded the expectations of just about any technology analyst who was asked prior to the device’s release.
