Hi, my interest in the Note was to be able to write s notes, and back them up. If I import a document (like a mail attachment), how do I get it into a type that can be written on with the S pen? I was able to convert a Word doc to a PDF, but still can't write on it. If I complete a doc, how do I back it up easily? Is Dropbox the only cloud option; so I how do I take an s note and move it to dropbox as a back up? Thanks.
