Apple achieved a rare feat and outsold Acer in the US this summer, new IDC estimates showed today. The company is estimated to have shipped almost exactly 2 million Macs just to the US in the quarter, beating out the combined Acer and Gateway's 1.95 million. Apple grew more than twice as quickly as any other US vendor, reaching 10.6 percent of the market after it shipped about 24.1 percent more Macs over the same time last year.
