The NPD market research group says that the lates version of the operating system, Leopard, is Apple's most successful yet, reports Apple Insider. In its first month on the shelves, sales were 20% higher than last year's Tiger release, despite promotion being stepped down a little. Tiger sold 30% more than the year before's Panther, which outsold its Jaguar predecessor by 100%.
"It's really stunning to see Apple have one blow-out OS launch after another," an analyst said. "It's clear that Apple has hit upon the right strategy for rolling out new versions of its OS." A more cynical commentator pointed out that pent-up demand may have helped sales figures —Leopard came out four months late.
