Although your NOOK has many unique features and capabilities, when it comes right down to it, its primary purpose is for reading books and other content. One of the benefits of owning a NOOK is that you can carry a complete library with you everywhere you go. If you don’t happen to have your NOOK with you, you can also read your ebooks on your PC, Mac, iPhone, iPad, iPod touch, Android phone, and Blackberry.
Various forms of content are available to read on your NOOK, such as NOOK Books, PDFs, and other EPUB ebooks. Appendix A, “Understanding ebook Formats,” explains more about the details of ebook formats.
