Worldwide PC shipments totaled 61.1 million units in the second quarter of 2007, an increase of 11.7% on year, according to preliminary results gathered by research firm Gartner. Figures from International Data Corporation (IDC) put the increase at 12.5%. According to Gartner, the worldwide market continued to be driven by strong consumer PC growth. Mobile PC demand remained strong, while Windows Vista's impact on consumer demand is considered to have been minimal. Hewlett-Packard (HP) remained the number one vendor based on PC shipments, accounting for 18.2% of worldwide shipments. HP grew faster than the worldwide market average growth rate for the ninth quarter in a row. HP showed steady growth across all regions and platforms.
Dell continued to struggle, as it experienced lower growth rates than the regional average across all regions. The major weakness continued to be derived from the consumer market. After dropping to the fourth position last quarter, Lenovo retook the number three position in the worldwide rankings from Acer in the second quarter. Lenovo significantly exceeded the worldwide average, showing stronger than regional growth across all regions except Japan.
