Dell's second quarter U.S. market share tumbled 19 percent from a year ago to 26.3 percent, but that was good enough to regain No. 1 in the U.S. over HP, according to IDC. Meanwhile, Acer and Toshiba's market share improved in the second quarter as Apple's slipped to 7.6 percent, down 12.4 percent from a year ago.
Overall, PC shipments fell 3.1 percent in the second quarter, but that's better than the 6.3 percent decline IDC expected. Gartner's tally has PC units falling 5 percent, an improvement from the 9.8 percent expected decline. The difference? IDC excludes x86 servers and Gartner counts them. Gartner also had Apple gaining market share, but it's unlikely that x86 servers are boosting the company's share.
Here are the big takeaways from the PC market share stats from IDC and Gartner:
Acer is surging due to netbooks and mini notebook PCs;
HP continues to surge courtesy of success in the consumer portable market and aggressive pricing;
