Is there an app that can convert a document (such as .doc, .ppt, etc) to PDF on the iPad? This is what I want to do: - Use a web browser to go to a class page - Download a lecture (.ppt most likely, though maybe some .doc files) - Convert the lecture to .pdf - Open the new .pdf file - Write notes (using a stylus) directly on the lecture slides - Possibly add new pages - Save the .pdf (including markup) and e-mail or upload to GoogleDocs so I can view it on a computer I would like to do all of the above using my iPad. Does anyone have any suggestions on which apps to get? I'm leaning toward Notes Plus for general note-taking, however that app does not appear to have the ability to import .pdf files. My biggest concern is being able to convert lectures to .pdf files directly on the iPad. I don't want to get one of the office programs because they are a bit pricey and I would not really use them very often. Thanks!
