TXT is crap. Apart from paragraph indentations you can't style it in any way. Well, actually you
can underline words if you use the next immediate line, like this:
TITLE
------
But that's about it... Plain TXT is simply a redundant format for an e-book.
Oh, and ASCII. I forgot about
ASCII titles. But it all goes to shit if you change the font.
PDF is good for academic quotes because they can imitate the printed page
and page numbers, which the other formats don't have (but they're looking into it). PDF can also be read on the Kindle
and everything else; not just MOBI on one/ePUB on everything else. Also, a tagged PDF can be converted with all the proper italics, bold, indentations, etc., in their exact places and it can also, theoretically, reflow on smaller text screens.
ePUB definitely has its advantages, except... It's looks different everywhere you look at it. It's like we're back in 1999 where every webpage looked different depending on which browser you used. We need a standard reading system, not 3 (Adobe ePUB, DRM ePUB and plain ePUB).
