I wonder how much of this information will be freely-exportable and copy able in the future. Or will we be stuck in "app silos" where all your information is tried to the App's data store and you can't get at it. If I'm using instagram for all of my pictures, will I always be able to take them with me when I migrate to a different platform/device?
