OneDrive's vision is to enable you to share and work together on all your files in a simple and secure way, inclusive of your personal files as well as the files you create and manage in shared space...
With the OneDrive web client, if I share an Adobe Photoshop or Illustrator file with someone, all someone needs to do is open the file in any browser. That user will then get a full-screen preview of the file without requiring the actual Adobe application to be installed on that device.

Stephen Rose so all of this is just for onedrive for business? If so why though, it makes no sense to me as a customer.
