The Amazon Kindle Book Reader is a device that allows you to read electronic books (ebooks) on a handheld wireless device.  Instead of reading a book by paper you read in on a screen instead making it much more eco-friendly.

Oprah has already said that she loves her Kindle Book Reader as it can hold hundreds of thousands of books at once and is a joy to read from.

The Kindle DX book reader is that latest Amazon Kindle and was released on May 6, 2009.  It is larger than the Kindle 2 and can hold up to 3,500 books.  Its other main benefits are the ability to read both vertically or horizontally by turning the kindle landscape or portrait.  It can also read PDF files which many customers have been asking for.
