IDC predicting massive global market share gains for Android smart phones this year and through 2015. They have Android down for 40% of all smart phones by end of 2011 and 45% in 2015. Apple's iOS hovers around 15% and slightly loses share. Symbian disappears almost entirely.
"Android is poised to take over as the leading smartphone operating system in 2011 after racing into the number 2 position in 2010," said Ramon Llamas, senior research analyst with IDC's Mobile Devices Technology and Trends team. "For the vendors who made Android the cornerstone of their smartphone strategies, 2010 was the coming-out party. This year will see a coronation party as these same vendors broaden and deepen their portfolios to reach more customers, particularly first-time smartphone users.
