Dropbox does a lot more than just store files. It provides a valuable abstraction over universal storage, through its integration with various services. For example, integration with MS Office to provide a single virtual drive to save my work to a single location from any PC i use.

DB adds tangible value.

And snapchat provides a valuable abstraction over picture moving that many people use. Does something need to integrate with MS office in order to be useful?

No but integrating with MS Office increases the likelihood that it’s valuable. Utility != value. Always ask yourself: who is my user? Am I providing them with a painkiller or a vitamin?
