In 2011 we saw iPads, Androids, and iPhones generate billions of dollars in new sales. On December 24th and 25th alone, more than seven million mobile devices were activated in the United States. Mobile is ramping up faster than any other technology we have seen in the past – eight times faster than desktop and laptop sales in the 1990s. By the end of 2012, it is predicted that 50% of the US population will have smartphones.
