Dawnfalcon, both of the filesets which I pointed you to include LaTeX.
I have no problem w/ ebooks being interactive and have often argued for it ---
http://aleph0.clarku.edu/~djoyce/jav.../elements.html is a favourite example of mine of the possibilities.
The problem w/ accepting the quick and dirty solution is that it becomes the new standard / lowest common denominator.
The bottom line here is there will be a continuum of formats:
plain text - reflows fine, little formatting
html / epub &c. - reflows, a reasonable amount of formatting, text display rife w/ poorly spaced lines and bad breaks and disconcertingly large empty spaces at the bottom of the display in multi-screen texts.
pdf - while reflow is possible (w/ limitations as pointed out here previously by others), strength of the format is total controllability over the formatted page and the possibility of good typography
