Abstract :
Globally, almost half the 175 million smartphones purchased in 2009 ran the Symbian operating system, and one-fifth were BlackBerries. Most of the rest, about 14 percent, run Windows Mobile, according to a February 2010 report from the IT research analysis firm Gartner. Developers who want to target the large and rapidly growing U.S. market, however, need to consider that the BlackBerry is by far the leading platform there with 42 percent, followed by Apple with 25 percent, while Symbian has less than 5 percent, according to research firm comScore.
