IDC today released forecasts for worldwide smartphone market and predicts that it's expected to grow 49.2% in 2011 as more consumers and enterprise users turn in feature phones for smartphones with more advanced features. According to the IDC Worldwide Quarterly Mobile Phone Tracker, smartphone vendors will ship more than 450 million smartphones in 2011 compared to the 303.4 million units shipped in 2010. IDC also published smartphone market share numbers that are bullish on Android market growth, with unexpectedly low market share predictions for iOS. They seem overly optimistic about Windows Phones because the world's number 1 phone maker Nokia will be making Windows Phones.
According to IDC, "Nokia's recent announcement to shift from Symbian to Windows Phone will have significant implications for the smartphone market going forward." "Up until the launch of Windows Phone 7 last year, Microsoft has steadily lost market share while other operating systems have brought forth new and appealing experiences," added Llamas. "The new alliance brings together Nokia's hardware capabilities and Windows Phone's differentiated platform. We expect the first devices to launch in 2012. By 2015, IDC expects Windows Phone to be number 2 operating system worldwide behind Android."
Here are the number predictions worldwide for smartphone OS market share:
