Completely agreed with the above; my point though was that right now for a large (actually very large) subset of e-books there are no good or even mediocre alternatives to pdf/djvu. This is why in talking about e-books I distinguish between 3 categories:
- text based - may contain images, simple graphics, footnotes, pictures and special characters and fonts, but they reflow nicely and any e-book format including Mobipocket, MsLit, Html (opf), Imp, Lrf will do for them and even txt and rtf at some marginal cost
- e-books for which the 2 dimensional structure is essential, like math books, art books, some fiction books as mentioned - for these I just do not see right now an alternative for pdf/djvu, unless you are content to make them image books and lose searching and other goodies - then anything like in point 3 will do, but you still lose reflowing
- image e-books (for example non-ocr'ed scans) - whatever the opinion regarding their legitimacy, the fact is that they exist and for them pdf/djvu while not essential is still the best solution since the question of reflowing does not arise; you can definitely use anything that admits embedded images (even simple html will do), but here pdf is convenient rather than necessary
