News Summary: IDC says Apple tablet share drops

HEADING DOWN: Apple's share of the market for tablet computers fell to 50 percent in the third quarter as the iPad faced more competition.

STILL UP: In the July-September period, Apple shipped 14 million devices, up 26 percent from a year ago. But its share fell because the overall tablet market grew by 50 percent.

FACTORS: Apple had no new tablets out in the third quarter. It also might have seen sales slow amid expectations of a smaller iPad. Apple could regain share in the holiday quarter with last Friday's release of new iPad devices.
