One of the major highlights of Apple's iOS 5 discussion at the WWDC keynote was "PC Free" a series of changes designed to make it easier for users to own an iOS device without the need for a Mac or PC for activation, syncing, and other activities.
Apple noted during the event that it is increasingly hearing from users who want an iPad or iPhone to be their only Internet-connected device, and changes such as on-device activation, over-the-air software updates, as well as app enhancements such as calendar creation/deletion and new photo editing features are making it easier for users to cut the cord.
