Apple has successfully held off Toshiba to claim a title as the fourth-best computer builder in the US for all of 2009, according to an early estimate from IDC. The Mac producer's market share grew just a tenth of a percent in the year, to exactly 8 percent, but was enough to fend off a surge for Toshiba from 5.8 percent to 7.7 percent. Apple is thought to have shipped 5.58 million computers to the country, or just 200,000 more than its Japanese rival.
