Part of the demand is being driven by businesses. Oppenheimer said the devices are being adopted by the enterprise "at an unprecedented rate"--75% of Fortune 500 companies are either deploying or testing it, including, Oppenheimer said, Xerox, ADP, Boston Scientific, Estee Lauder, Rite Aid, and Disney.
The iPad is also making traction in the schoolroom. Schools picked up as many iPads as they did Macs last quarter, Cook said. "This was surprising to me," he said. "K-12 is even more conservative than enterprise in adopting new technology."
The iPads' performance in the educational market "really demonstrates what kind of opportunity there probably is there," he said.
Apple reported yesterday that it can't keep up with demand for the iPad 2.
