iPad To Dominate Tablet Market Until 2015

The iPad will continue to dominate the growing tablet market until Android tablets take over in 2015, according to forecasts from Informa Telecoms & Media.

The study estimates that Apple currently owns about 75% of the tablet market, which is expected to expand from less than 20 million units in 2010 to more than 230 million in 2015. By that time, Apple’s share of the market will drop to just 38%, due largely to the proliferation of cheaper and more advanced Android tablets. Still, it will take another year — until 2016 — for Android tablets to outsell Apple ones.

RIM’s prospects for market expansion are less optimistic, the study finds. Once the PlayBook begins supporting Android apps and 4G connectivity — HSPA+ and LTE versions are expected before the end of 2011 — sales are expected to improve.

Other analysts are more bullish on Apple’s market dominance. A study released by Gartner in April predicted the iPad will maintain a 47% share of the tablet by 2015, with Android hovering just above 38%.
