So just to be clear: Is this just making it a lot easier to open the doc in the iOS Word app and saving changes to Dropbox or is it like putting Word within the Dropbox app allowing changes to be made directly from within the Dropbox app?
If it's just going to take you to the Word iOS app, won't that still require an Office 365 subscription to fully use?
