There are typos and mistakes in the e-book that make it difficult to read. Also, in the hard copy book some key sentences are "pulled out" in the margins as highlights, but in the e-book, these are just included in the regular text. You end up reading the same sentence twice which is very irritating and distracting. These should be removed altogether if they cannot appear graphically as they do in the hard copy. I was looking forward to the e-book format, but am disappointed in it. I don't know if I will get another from Christianbook.com. I does not seem as if anyone is reviewing them for how well the hard copy format has transferred to an e-book format.
