Kevin Fox expects Apple to unveil huge changes at WWDC – MacDailyNews - Welcome Home:
• Seamless remote access to any data kept in your Documents folder, and synchronization across machines.
• Universal login using your Apple account: Walk up to any Mac, sign in as a guest using your Apple account credentials and you’ll be brought to the same desktop you get on your personal machine.
• iOS runtime within Mac OS to allow iPhone apps to run as Dashboard widgets and iPad apps as first-class desktop apps.
• Your canonical music library exists in the cloud. Your Mac, Windows, or iOS device can sync with all or part of it in the same way that your iOS devices sync with your computer’s iTunes library today.
• Unification of the App Store to encompass Mac, iPhone, iPod, Apple TV and iPad apps.
• Stripping out the App Store from iTunes. iTunes will be the media storefront and the App Store will be the resource storefront.
