I've yet to purchase one of the proprietary e-book readers so I can't speak from personal experience, but botched conversions appear to be commonplace. If you browse through Amazon listings, there are many 1-star reviews of otherwise fine books that refer solely to the deficiencies of the e-book version formatting. You get these kinds of complaints often in the software world, where it can be difficult for developers to take into account the almost infinite combination of PC hardware configurations, but the readers do not have this problem. I seem to recall a tweet from a publisher referring to an article explaining why these conversions are much more difficult to do right than one might suppose (wish I had read it!).
Anyway, for those of you who have ordered new release Civil War e-books, what has your experience been like so far? Have publishers been able to format text, illustrations, maps, footnotes, etc. to your satisfaction?
