DataViz attempts to fill a very large hole in functionality for mobile business users. Editing word docs on the go is a very important part of life for any mobile professional.  With that said, syncing your documents and getting them into a third party app is a very tough hurtle to overcome for IPhone developers. Apple doesn’t provide the option to do this from within the native mail application. Therefore, IPhone users are unable to create/edit a native word document or even send that document as an attachment.
