This is a crazy figure: 50% of the iPhones brought to Genius bars have never been connected to a computer. Ever. I don't know about you, but I can't understand how people can live without synching between devices or backing up.
Since the Genius bar is what most people use to service their iPhones, I'm going to assume that this is representative of the whole iPhone population. If former Macworld Associate Editor David Chartier's source is right and this percentage is real, iCloud will not only be cool. It will be a potential savior for half of the iPhone users. [onefps]
