For the full year, HP saw its shipments fall by nearly 5 percent; Dell’s fell by more than 8 percent; and Acer’s fell 30 percent in the U.S.So who grew? Apple. It saw its shipments grow by 18 percent in the quarter, according to IDC, and by 21 percent in the Gartner report. As of the end of the year, IDC said, Apple’s share of the U.S. market amounted to 10.7 percent, which is up from 8.8 percent a year ago.

It’s also important to consider the Mac sales are, at this point, smaller than the contribution iOS devices make to Apple’s bottom line. Yet by making products that consumers actually want, Apple’s been able to expand and improve its position in the PC market.
