First of all, entirely ignore Rich's Goodread's link (sorry Rich). It is comparing the Kindle Paperwhite with the original Nook Simple Touch Glowlight. That model is long gone. (The sequence is B&N leap frogged Kindle by coming out with the Simple Touch Glowlight. Amazon then leap frogged B&N by coming out with a much improve version of the same thing (reviewed by Goodreads). Since then, B&N has come out with a new model, the Nook Glowlight. Basically, Theo has it right, there are only subtle differences between the two current models - nothing that is a game breaker.
Looking beyond the devices themselves, Kindle advertises having a MUCH larger number of ebooks available. As far as I can tell, many of these are self published books, but also include some earlier books by current authors. Advantage Kindle.
Barnes and Noble allows you to view any ebook (the entire ebook) that they publish for an hour while in one of their stores. (Both companies allow you to see free previews.) This can be important in that a few of the previews do not go beyond a table of contents or a table of contents and a preface not written by the book's author. Of more interest, it is sometimes very useful to see how readable maps found later in a book are or how well photographs and illustrations are displayed before buying an ebook. Advantage Barnes and Noble. (Tongue and cheek, if you are a complete freeloader, you can go back to Barnes and Noble every day for an hour and read an entire book for free.)
****************
Some posters have suggested getting a tablet instead. Briefly (and IMHO), the advantages of a Paperwhite or GlowLight ...
- Cheaper
- Much lighter
- Much better in bright daylight
- You only need to charge them about once a month (constantly having to charge a tablet gets old)
Advantages of a tablet
- Much more versatile, you can check email, the net, a weather app, etc. (Oh yes, and TUG too.)
- Book illustrations will be in color
- While the ereaders come with built in dictionaries, these dictionaries will often not have foreign words, proper names (places, historical figures, other authors). The tablets will give you a chance to automatically search out a word on Google or in Wiki.
Something to be said for both.
