In order to orchestrate this, they will need a central repository of their data, that they can search around, and is hopefully organized (ie, they remember that their picture was taken in 1997 at that trip to Chicago, or that the song was a rock song they heard on the radio in highschool).
Apple, recognizing this need, will release a new app that will allow users to create hierarchical categories for their stuff, search their stuff, move it around, and make copies of their stuff. The app will probably be named "Finder", and these pieces of data might be named, "files".
