In a new quarterly report tracking the burgeoning tablet and e-reader markets, technology research firm IDC said tablet shipments grew 45% in the third quarter to 4.8 million worldwide. The iPad continues to own the segment, accounting for a full 90% of tablets shipped.
With the arrival of the Galaxy Tab and host of competing devices coming this year from Motorola, Research in Motion and other manufacturers, though, Apple's market share is likely to contract in 2011.
IDC projects tablet shipments worldwide to nearly triple to 44.6 million this year from 17 million in 2010, and to hit 70.8 million in 2012. Growth in 2011 and beyond will be driven by vendors launching media tablets based on Android and other operating systems, as well as price and feature competition, and strong demand from both consumers and business users.
