You can covert any document file into pdf format with the help of applications. But in same way you can do it very easily in the Microsoft word document file. Just save that file into pdf format or ebook format as per your requirements.
Very true, or simply remove the DRM. While the act of removing the DRM is not legal I know many who will remove the DRM once they legally purchase the ebook simply to avoid the issues and concerns previously mentioned. DRM exists to foil the illegal copying and DISTRIBUTION of the book to non-paying readers. It exists ultimately to protect the publisher/author's right to income from the book. I am completely cool with that.
