WWDC '13: Apple keynote, by the numbers

Apple chief executive Tim Cook and other executives took to the stage in San Francisco's Moscone Center to announce the latest and greatest from the Cupertino, Calif.-based technology giant.

On deck include the latest software announcements for developers to take advantage of the latest features in its new mobile and desktop platforms, iOS 7 and OS X Mavericks. 

During the keynote, the company's management, lead engineers, vice-presidents and key personnel dished out the latest numbers, from sales and shipments through to financials and other figures.
