Don't underestimate the significance of Apple's iBooks 2, textbooks for
that app, and the free ibooks Author to produce such books.

One report (see macrumors.com) claims that Apple sold 350,000 copies of
their already-existing textbooks the first three days. These are all
high-school math/science titles -- including one, "Life on Earth", still
in progress.

Especially if Apple ports iBooks 2 to Macs -- which may be important
given how many college students have Macs, including MacBooks -- the
college market could be the next big target.

It's a shame that(La)TeX gets the short end of things with iBooks
Author. (But how _would_ you expect to incorporate LaTeX typeset
material into such a rich page layout authoring tool?)

What is compatible with iBooks Author -- and can be called directly from
within it -- is Design Science's "MathType" application. You create the
math expressions in MathType, and they are transferred to the iBooks
file you're creating as MathML, which the iBooks format can interpret.

That suggests possibilities, e.g., creating LaTeX as usual, using some
tool (e.g., MathJax) to convert to MathML, which is then interpreted by
the iBooks format.

Of course this _seems_ to mean you won't do a whole document first in
LaTeX -- just the math-like expressions.
