In this 40 minute video Mr. Bazargan proposes TeX as a way to render math equations and to handle line breaking better through TeX's advanced hyphenation and justification handling.
TeX is apparently ideal because it's light and because many typesetting challenges to other engines are just native to TeX. Part of the idea I guess is to extend eBooks beyond novels. And that's an interesting area; I read somewhere that Governator wants to phase out paper textbooks and use digital books in California schools.
I'm not an expert on any of this, I just see a lot of talk about eBooks and the future of reading in the forum. So what do you guys think?
