Well, I do not disagree about formatting (although when the font size/zoom automagically switches from Medium to Small when turning the page, it is a bug and not a feature). But I can certainly understand the deal with the page sizes.
However, when the Reader takes several seconds to turn a page on relatively
simple PDFs formatted for the Reader's page size, that's a whole other matter. That's what I call unacceptable. The LRF viewer knows how to paginate the LRF files, why didn't Sony suggest that Adobe implement a similar algorithm for PDF? Take a large image heavy PDF, and the page turning time goes to
munutes!
The Reader's UI is frozen while this parsing is going on, one cannot do anything to stop or interrupt (other than RESET of course).
If I am not mistaken, the Open Source PDF parsers on iLiad and Hanlin Lbook V3 do a better job displaying PDF than the Adobe's own viewer on the Sony Reader. That's pretty bad.
