I don't think that it was her who decided every detail in the layout of her pbooks. Most likely, it was all done by typesetting professionals who prepared several nicely looking dummies and asked her to choose which one she prefers.
Mobi might not support every feature of epub but it is not a reason to reject mobi format because the differences are not very significant.
E-readers require change of typesetting philosophy. There is no use to trying duplicate every feature of print typography. Font embedding could be a nice feature but it is optional because the power of an ereader is to choose the fonts of your liking. A publisher no longer can force such things on readers and they have to invent a different approach to provide the best reading experience. For example, I would like to see a possibility to provide automatic footnotes. It should not be too difficult to provide a footer or a running head whenever the text requires it.
