Computer sales will rebound so quickly this year that they should reach an all-time high, researchers at IDC estimated today. The year-over-year growth in sales should reach 19.8 percent, outweighing the slump in 2009, and could see 354.8 million computers ship worldwide. Most of these would be notebooks, which could grow 28.6 percent while desktops should grow by just 8.2 percent.
