About 120 million PCs will be replaced this year, according to The Gartner Group, with 140 million more computers likely to be replaced next year. This represents a 13.6 percent rise in PC shipments worldwide this year and 9.8 percent in 2005. Aging personal computers — more than 30 percent of which are at least three years old — and growth in the U.S. and Asia are responsible for the increase, the group notes in the “PC Forecast Scenarios” report for 2004/2005. The U.S. Department of Commerce is also predicting personal computer sales will rise. “All this means computer makers like Dell, Hewlett Packard, IBM and Apple are poised to rise,” CBS Marketwatch reports.
