  1. Reading Device. Most of us would like to read eBooks on multiple devices. With DRM,You can only read eBooks on one single device or app.
  2. Sharing. We always want to share the same eBook if one of our friends or families already have one. But DRM doesn’t allow you to share the books with others.
  3. Back up your books. Although you purchased the digital contents legally from the book store, the DRM protections do not allow you to back up and have full use of them.
  4. Conversion. You cannot convert DRM-protected books to other formats like EPUB or PDF that can be read in other apps.
