That was quick. In less than 24 hours Apple has confirmed that over one million users bought and downloaded Mac OS X Lion.  

“Lion is off to a great start, user reviews and industry reaction have been fantastic,” said Philip Schiller, Apple’s senior vice president of Worldwide Product Marketing. “Lion is a huge step forward, it’s not only packed with innovative features but it’s incredibly easy for users to update their Macs to the best OS we’ve ever made.”

The new operating system, which is only available by download, will have made Apple a cool £21m. 

That's 41,666 copies of the new operating system an hour, or 11 copies a second from users around the world.

Earlier in the week we estimated that if all 25m Snow Leopard Macs opted to download the new OS, Apple would have to serve 100 petabytes of data.
