The Sony Reader was launched in October 2006 in the U.S. for US $350.
The Sony Reader was the first ebook reader to use the new advanced E
Ink screen technology, "a screen that gives an excellent reading
experience very close to that of real paper, making it very easy going
on the eyes" (Mike Cook, editor of epubBooks.com). Another major
feature of the reader over most other electronic devices is its battery
life, with over 7,000 pages turns - or up to two weeks of power - on
just one battery charge. It was the first ebook reader to use Adobe's
Digital Editions. The Sony Reader is presently available in the U.S.,
Canada, UK, Germany, and France, with cheaper and revamped models.
