Roughly the size of a paperback, the Sony Reader features an electronic paper display and can store hundreds of books and other documents using a combination of internal flash memory and optional Memory Stick.

In addition to e-books offered through the Sony Connect service, the Reader can also store and display personal documents in Adobe PDF format as well as JPEG photos.

As part of the deal, Borders customers will also have the opportunity to purchase prepaid cards, redeemable online for a broad selection of trade fiction and non-fiction e-books.

In addition to e-books, the Sony Connect service will offer Borders customers who buy the Sony Reader access to a broad selection of web content in the form of blogs, news feeds and online magazines, said Lee Shirani, vice president of Sony Connect Inc.
