I agree with you, and that's one of the reasons I prefer to use the MobiPocket format, because that's the approach that Mobi takes - don't "hard code" such things as font, justification, margins, etc, in the book (unless it's vital) but leave them for the user to choose. With a Sony book, on the other hand, it's all "hard coded".
