I believe the main uses are:
1) Backup of i devices
2) Storage of music, video, TV etc. bought through iTunes or matched using the match feature
3) Storage of data in applications on i devices I.e. Pages and numbers
4) Sorage of pictures taken on iPhones (photo streaming) which are on the iphone camera roll. They automatically appear on iPads, PCs and Macs.
I do not believe that it is for storage of absolutely all data. I tend to use it mainly for keeping calendars in one place on my iPhone and iPad and for storing a copy of of other data on my iPad/iPhone.
