Apple's Worldwide Developers Conference (WWDC) is scheduled to take place in San Francisco June 11-15, 2012. As expected, Apple will be holding a keynote address on June 11, which will more than likely be hosted by the company's CEO Tim Cook and his junior executives. Apple has so far not said what will be discussed at the keynote address, but has hinted that the company's Mountain Lion operating system and mobile iOS will be part of the talking points at the event. For consumers, the Worldwide Developers Conference is a major event. In the past, Apple has used the event to unveil a new iPhone. In addition, it's usually the soapbox for heralding Apple's latest improvements related to its iOS and Mac OS X. For CIOs, however, the Worldwide Developers Conference can be a bit of a concern. The show has delivered some promising new developments for corporate users, but it has also hurt productivity with obsessed Apple fans tuning into updates from the show when they should be working. But that's far from the only reason CIOs have to fear WWDC.
