Dropcaps? I think even Pagemaker 1.0 could already handle those back in 1985
Seriously though... I understand that 5 or 6 inch ereaders aren't capable (yet?) of displaying complex layouts. Somehow I had expected that 20 years of experience with the PDF file format and HTML would have allowed the industry to come up with a standard that would be way ahead of the hardware. That doesn't really seem to be the case.
