The iPad's dominance of the market for tablet computers may prove short-lived

APPLE is due to launch a new version of its popular iPad on March 2nd. The company sold some 15m iPads in 2010, the year in which the device was launched, and according to one forecast it could sell more than 40m of them in 2011. But other tablet computers, in particular those based on Google's Android operating system, are expected to erode its share of a fast-growing market. In 2010 iPads accounted for about 80% of total tablet sales; by 2015 Apple's market share could fall below 40%.
