History of E Ink:
2004 Sony introduces Librie in Japan and it bombs
2006 Sony introduces their Reader and it sells
2007 Amazon introduces Kindle with best sellers priced at $10. Market takes off.
2009 Barnes & Noble introduces nook
2010 Apple speculated to introduce tablet

Consensus a/o December 2009 is there is no clear winner.
Evaluations are very subjective, so it is hard to make a recommendation.

- May be easier to use. Tactile keyboard.
- Internet access thru sprint G3
- Faster

Nook has:
- Lending Books
- 3.5" Color Touchscreen to browse covers and navigate screen.
- Android Operating System

Kindle DX
- Better for textbooks, magazines and newspapers. (Students)
- Very bad keyboard
- $489 (expensive)

"I own both the Sony Reader and Kindle 2 and can't wait to replace both with the Apple tablet. E-ink displays are slow, lack contrast in all but the best light, and are very fragile."

The touchscreen layer on the Sony introduces an annoying reflective glare that's almost impossible to eliminate in any light.

Sony Reader Daily Edition - 7 PRS-900 review at

Kindle DX Reviews: Summary:
Hair-trigger orientation sensor (switches to landscape with 45° tilt)
Awful keyboard.
No way to zoom pdfs (except switch to landscape)
The core experience of simply reading a book is somewhat more pleasant, all of the Kindle 2's limitations are still front and center.
Amazon has announced in May that it "reached an agreement" with the three textbook publishers who account for 60% of textbooks sold--Pearson, Cengage Learning and Wiley (but not Houghton Mifflin Harcourt) to produce kindle DX versions of their books, but none have shown up as of Dec., 2009. Summary:
Some pros:

  • PDF Support - Official Adobe PDF support, reviewers note that PDF documents look great. Also, searching a PDF highlights the found terms. Plus page numbers for PDFs.
  • Large Screen - The 9.7" screen is a great size.
  • Auto-rotate - looks to be a good, solid feature.
  • You can change the font size, the number of words per line and the spacing between lines.
  • Free Wireless Internet - WhisperNet (in Sprint coverage areas).
  • Long Battery Life. 4 days with wireless, longer without.
Some cons:
  • No color
  • For PDFs, text to speech, dictionary and 5 way controller don't work. There are also no annotations or highlighting for PDFs. And there is no Table of Contents.
  • Note-taking is painful. It's nothing like just jotting down notes.
  • The keyboard sucks.
  • Screen Refresh Speed Summary:
- In the May, 2009 announcement, Jeff Bezos made it clear that the DX was targeted largely to students requiring textbooks and professionals accessing business documents.
- DX's 9.7-inch screen resembles a page from a typical hardback.
- Reading a long newspaper article on the DX can be daunting, as it appears like a dense block of text.
- By elegantly supersizing the Kindle - and ramping up its ability to read files - Amazon has improved the best all-around e-reader available.
