Nook sounds closer to book, but I personally prefer Kindle. What about the book munching Albert Mohler?
These reviews are a bit old but still interesting from a heavy reader’s perspective.

By the way, Amazon have dropped the price of the bottom end Kindle to $114 USD — the catch? It comes with minor advertising. I find Amazon’s targeted advertising pretty good so it seems like a no-brainer.
