According to a recent report from Forrester Research, Apple’s iPad tablet PC will continue to lead the tablet market through 2016 despite increased competition. The Cupertino-based company’s iPad is expected to account for 53% of the global tablet market in 2016, at which time emerging markets may account for nearly 40% of all tablet sales, The Financial Post reported on Monday. Over the next five years, the global tablet market is estimated to increase to 375 million devices, up from 56 million sold in 2011, for a total global base of more than 760 million tablet owners. The report identifies Amazon’s Kindle Fire as the only viable alternative to the iPad, while devices from Google and Research In Motion are said to be failing to keep pace with Apple’s tablet. Forrester also indicated that by 2016, about one-third of all tablet sales will be for businesses, accounting for roughly 122 million units.
