After trying out a few different EPUB readers on iOS (iPhone), I think
this is simply a quality-of-implementation issue with iBooks. For
example, NeoSoar's reader is much more responsive with the same file on
the same hardware. Its page counting is much more nonsensical, but that
just seems to support my earlier theory.
