From the New York Times:
The two leading analysis companies tracking the PC industry just delivered their reports on the fourth quarter of 2013, and it was bad.
Gartner had worldwide PC shipments for the quarter at 82.6 million units, a drop of 6.9 percent on the number a year ago. It was the seventh consecutive quarterly decline, Gartner said. IDC put the figure at 82.2 million units, a drop of just 5.6 percent, and less bad than the 6 percent the firm had earlier expected.
