20m Vista copies sold
Microsoft on Monday said it sold more than 20 million copies of Windows Vista in the first month since its debut in late January, revealing that customers are adopting the new operating system at more than double the rate of its predecessor -- Windows XP. "It's a little bit better than what we were expecting," said Windows marketing group director Bill Mannion. The speedy adoption of Windows Vista comes just before Apple plans to release Mac OS X 10.5 Leopard, the next generation of its own operating system that will serve as the company's answer to Microsoft and bring Intel-based Mac owners the ability to install as well as boot Windows on their Macs. Microsoft was surprised by how many Vista customers chose to purchase the premium versions of Vista, according to Reuters, as company chief Steve Ballmer said analysts' forecasts for revenue from the new operating system were "overly aggressive." Some industry watchers expect Apple to launch Mac OS X Leopard at a special event planned for the NAB convention in Las Vegas, Nevada.
