Global PC shipments will climb nearly 3% in 2009, but declining prices will mean that revenue will dip nearly 11%, according to IT research and advisory firm, Gartner Inc. Worldwide personal computer shipments will total 298.9 million units in 2009, up 2.8% from 2008, the firm said. A surge in PC sales during the third quarter of the year has forced Gartner to reassess its earlier predictions that shipments would fall 2% this year. 'The unexpected increase is most likely due to a reduction in the price of PCs, something that will also have an impact on revenue for the year,' Gartner said.
