From the first quarter of 2008 to 2009, several PC manufacturers saw growth in the market, with notable increases in units shipped. Hewlett-Packard grew 3.6 percent year over year worldwide; Acer made the biggest gains worldwide, growing 23.7 percent; Toshiba grew by 10.5 percent; and even Lenovo grew by 2.9 percent.
Dell, meanwhile, took a hit from 2008 to 2009 in the worldwide market. The PC maker went backward, with shipments dropping 17.1 percent, which IDC says is mostly due to the slow consumer market. However, even with the decline in shipments, Dell was able to regain the title of biggest PC maker in the U.S., claiming 26.3 percent of the market -- even though its domestic shipments fell 18.9 percent -- edging out second place HP by 0.3 percent
