Motorola escalated the rhetoric surrounding the Xoom tablet on Monday with a new teaser video (below) for its upcoming Super Bowl ad. The minute-long video accuses Apple of hypocrisy for its own famous Super Bowl ad and claims that "2011 is a lot like 1984" after what Apple did with the iPad. Apple imposes "one authority," uses "one design" and offers just "one way to work," the teaser suggests using a world framed by iPod earbuds.
