3 Million, 4 Days
Apple:
Apple today announced that downloads of OS X Mountain Lion have exceeded three million in four days, making it the most successful OS X release in Apple’s history.
For some context, Apple announced that OS X Lion sold one million copies in one day — which might imply it was selling a little faster than Mountain Lion. But by October, about two months later, Lion had moved six million copies. Mountain Lion is selling faster — seemingly much faster.
