As of November 2011, 91.4 million people in the United States-owned smartphones, according to comScore. That was an 8 per cent increase over just a few months before. And if the trend continues, as most analysts and smartphone vendors believe it will, the number of individuals in the United States with a smartphone will be close to, if not exceed, 100 million by March 2012 - that's nearly one out of three Americans. And that's not including the number of people using iPads and tablet PCs, which was well over 15 million as of June 2011, per CTIA, the Wireless Association.
