Android will rise to be the second most used mobile OS in the world by 2013, according to a new IDC estimate. Analysts still expect Symbian to hold on to its lead but that Google's OS will have grown 100 times larger since starting off in 2008, reaching 68 million phones three years from today. The prediction doesn't immediately gauge the position of BlackBerry, iPhone or Windows Mobile but expects all three to be eclipsed.
