Apple's Slice of the U.S. Computer Pie Drops to 8%

"Apple's share of the US computer market fell to 8 percent during the fourth calendar quarter of 2008 from 9.5 percent in the third as the Mac maker surrendered its third place ranking to surging netbook maker Acer, according to market research firm Gartner."

Acer jumped ahead of Apple per Gartner, from the sounds of it with lots of help from their netbooks, with a whopping 55.4% growth. However, based on this data, Apple is still one of only three of the top PC vendors that had positive growth in the 4th quarter of 2008, Dell and HP both declined.
