People often forget that PDF is not a "document" format, but a printing format. If you want to work with a document format, that's universally accepted, you work with RTF. DOC/DOCX from Microsoft are monstrosities just like PDF - and just like in PDF, also in DOC/DOCX you can embed anything (movies, pictures, executables, flash, God and the multiverse, etc etc). A printing format is something finished, that you don't go back from. Or you can try to go back from, but you get a lot of pain in return. Hence your previous startup problems.
