fwiw, i know the topic of the thread has deviated, but i share the frustration about reading PDFs on my device. In my case, it's an accessibility issue - I can't see well, so zooming with reflow would make my life materially better since I'd be able to read research papers on my morning commute.
Sometimes users have needs that may seem superfluous and beg for a snarky reply, but there are often important reasons behind them, even though they may not be actionable.
I'd pay $x000 for an app that does some sort of intelligent pdf-to-epub conversion that doesn't require human-in-the-loop management/checking.
