Apple dominates tablets market

Apple continues to dominate in tablet computers although its market share is shrinking because of growing competition, according to a research group.

IDC said today that Apple shipped 22.9 million iPads in the October-December quarter, during which it released a smaller version and updated its full-size models. That is a growth of 48% from the same period a year earlier. But Apple’s market share fell to 44%, from 52%.
