[OtterBooks]

If recreating the visual experience of a paper book is your primary goal, I would go with the Nook Classic ereader. If you want a low cost portable media experience with color, viable web surfing and a degree of interactivity, or even if viewing color documents is important to you, go with a media-tablet such as the Nook Color. Unfortunately right now you can't get both in the same device.

Aside from being based on an entirely different kind of technology than the Nook Color, the Kindle 3 is disqualified for any of the above uses if you want library access (without file alteration).
