"The worldwide PC market in the fourth quarter performed well. It managed to produce double-digit growth rates both year on year, as an indication of continued expansion of the installed base, and sequentially, largely as a result of year-end holiday sales and strong consumer activity." - David Daoud, research manager, United States Quarterly PC Tracker and Personal Computing CIS program
