A look at the history of the U.S. smartphone market reveals just how quickly leadership positions can change over time. In 2005, Palm was the smartphone market leader at 35 percent, followed by RIM and Symbian. By 2006, Microsoft had emerged as the leader, only to be surpassed by RIM in 2008. In 2011, Android surged to the lead, followed by Apple. Notably, while the lead has switched hands many times, Apple has never claimed that mantle.
