Is Dropbox just making use of iOS libraries (iBooks code?) to read .doc/.docx files and view them?
Or did Dropbox actually have to code some kind of wrapper to get .doc/.docx files to display properly?
The web version of Dropbox just downloads the file so seems like whatever the viewer is it must be iOS-specific,
thanks,
