The Sony Reader is an e-book reader. It uses an electronic paper display developed by E Ink Corporation that has 166 dpi resolution, eight levels of grayscale, is viewable in direct sunlight, requires no power to maintain a static image, and is usable in portrait or landscape orientation. The reader uses an iTunes Store-like interface to purchase books from Sony Connect eBook store.
It also can display Adobe PDFs, ePub format, personal documents, blogs, RSS newsfeeds, JPEGs, and Sony's proprietary BBeB ("BroadBand eBook") format. The Reader can play unencrypted MP3 and AAC audio files. The digital rights management rules of the Reader allow any purchased e-book to be read on up to six devices (at least one of those 6 must be a PC).
Although you cannot totally share purchased eBooks on other people’s devices and accounts, you will have the opportunity to register five Readers to your account and share your books accordingly. At this time Sony has no plans to introduce time-expiring books in the U.S. The sony Reader competes with other e-paper devices— the Amazon Kindle, iRex iLiad, the Jinke Hanlin eReader, and CyBook by Bookeen.
I really like my "collection". I have an old pocket reader, which I love, and a touch, which I also love! I am using the touch now to start reading the Sharpe series again!
