My wife gave me a nook, rather than a kindle, because she hates Amazon and what it represents. (Don't get her started, please)

It works great. Battery lasts so long that I often forget that I have to charge it. There is a huge and searchable catalog of free books that I can get, many of which are about adventure travel and hiking. And it is light enough that I have actually considered bringing it backpacking.

No, not for me--I fish. For my wife, so she can read while I am fishing!
