Last year, Amazon surprised many pundits and the public by claiming strong Kindle Fire tablet sales of more than a million per week
during the holiday season, doubling overall 2011 sales. A new study that compares ad impressions in mobile apps compared that sales period to the current ad impression rate of the iPad mini and found that it garnering 50 percent higher activity
than the peak of Kindle Fire sales. Calling the iPad mini a "game changer," Millennial Media
safely predicts the iPad mini will emerge the winner of the gift wars this holiday season.
