FRAMINGHAM, Mass., January 12, 2011 – The worldwide PC market continued to slow in the fourth quarter of 2010 (4Q10) due to a softening consumer market, competing products like Media Tablets, and strong year ago sales. Despite a holiday season marked by a long promotion cycle and highly competitive price points, the global PC market saw shipments rise only a modest 2.7% year on year during 4Q10, according to the International Data Corporation (IDC) Worldwide Quarterly PC Tracker. Fourth quarter growth was slightly less than a projected increase of 5.5%, but shipments of 92.1 million for the quarter still were the largest ever. Total shipments for 2010 reached 346.2 million, an increase of 13.6% that was fueled by a strong recovery in the first half of the year.
