The worldwide smartphone market is expected to grow 49.2% in 2011 as more consumers and enterprise users turn in their feature phones for smartphones with more advanced features. According to the International Data Corporation (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. Moreover, the smartphone market will grow more than four times faster than the overall mobile phone market.
"Overall market growth in 2010 was exceptional," said Kevin Restivo, senior research analyst with IDC's Worldwide Quarterly Mobile Phone Tracker. "Last year's high market growth was due in part to pent-up demand from a challenging 2009, when many buyers held off on mobile phone purchases. The expected market growth for 2011, while still notable, will taper off somewhat from what we saw in 2010."
