The point you are missing is that the ereaders are behaving well. They
are following the epub
standard, and that to the letter of the standard. The problem is that
the standard does not
enforce any particular implementation. If you look at the slow progress
of the standard that
actually requires a full implementation of the HTML5 standard. That
wait will very long.
Furthermore, ereaders are made by companies more interested in profits
than spending a few Euros
more to put decent HTML engines into their readers. Why they do not do
that is beyond me!

I always to like to look at programming as modular and would think that
a epub/ebook module would be nice that maps
there are commands for layingout ebooks. these commands can then be
mapped back to standard context commands.
For some interested in producing a epub then can use the conventions
for producing ebooks and ConTeXt can provide the
math conversions to regular page dimensions used in PDFs for proofing
or creating a printed version. It would also make the
creation of EPubs from ConTeXt a simple parsing exercise.

Keith.
