Since Wednesday 12 October 2011 Apple iPhone, iPad and iMac users are not very productive.
They are too busy updating their iPhone/iPad software to iOS 5, their Mac(s) to Lion 10.7.2. After that they have to wait for the move from mobile-me to iCloud. Due to high traffic this Apple service is restricted (try again later please).
Do you have any idea how much this update the world costs?
