Is that because nice hyphenation/justification is CPU-intensive?  Or some 
other reason?  Seems like doing these things happens in TeX pretty fast 
these days, so it's not a per se user-interface issue (assuming you could 
use TeX inside an eBook).  Or is it just that the algorithms are gnarly?

Thanks.
