The worldwide smartphone market is forecast to grow 55% year over year in 2011 as a growing number of users turn in their feature phones for more advanced devices. According to the International Data Corporation (IDC) Worldwide Quarterly Mobile Phone Tracker, vendors will ship a total of 472 million smartphones in 2011 compared to roughly 305 million units shipped in 2010. That figure will nearly double to 982 million by the end of 2015.
The fast-growing smartphone market, which will grow more than four times the rate of the overall mobile phone market this year, is being fuelled by falling average selling prices, increased phone functionality, and lower-cost data plans among other factors, which make the devices more accessible to a wider range of users.
