e-paper devices

The Sony Reader is an e-book reader manufactured by Sony. It uses an electronic paper display developed by E Ink Corporation that has 166 dpi (200 dpi in 5 inch version PRS-300) resolution, eight levels of grayscale (16 in the PRS-900 model), 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 (currently US and Canada only). 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 MP3 and unencrypted AAC audio files.

The Sony Reader competes with other e-paper devices: the Amazon Kindle, iRex iLiad, the Jinke Hanlin eReader, CyBook by Bookeen, and the Barnes & Noble nook.

Operating systems

Windows

Sony Reader comes bundled with Sony's proprietary software called Sony eBook Library (formally called Sony Connect). It is similar to iTunes in nature and requires Windows XP or higher (Windows Vista or Windows 7), an 800 MHz processor, 128 MB of RAM, and 20 MB of hard disk space. This software does not work on the 64-bit versions of Windows XP. 64-bit Windows Vista and Windows 7 is supported since Sony eBook Library version 2.5.00.09170 for all but the 500 models.^[12]
