The mythical white iPhone 4 may or may not have been cancelled, but that hasn't stopped speculation about what the iPhone 5 is going to bring us next year.  The latest rumor comes from the folks at Cult of Mac, who report that Apple is planning to use a near field communication (NFC) chip in the iPhone 5 to allow for remote computing.  The iPhone would contain the owner's data and settings, as well as applications and music libraries stored in the cloud, which could be loaded up on an NFC-equipped Mac and allow the user to work as if they were on their own machine.  Of course, you would have to be pretty close to the Mac to enable the feature, and the process would require authentication.  When you're done working, you could walk away from the computer and it would return to the state it was in before your interaction.

NFC is a well-known way to make credit card payments, but this new use could open up a ton of new users to remote computing and basically eliminate the need for virtual network computing, or VNC, clients on the App Store.  There may be some concerns about security, especially if a user's passwords, bookmarks, and other data would be stored on the iPhone, even with a required authentication process, so hopefully Apple could figure out some way to secure the data.  Have any of you used NFC in the past?  Would remote computing with NFC be something you'd be interested in?
