That's all there is to it - I'm not letting Calibre or Sony Library near my journal article PDF library (not that the Sony Reader gives justice to such PDFs anyway).
I've tried it in the past and when I apply PDF reflow often all you get is an OCR munged text that doesn't make sense - makes you wonder what the professional journal publishers do all day..
It's a shame because I'd love to read journal articles on something like the Sony Reader - guess I'll have to wait for a ereader with an A4 sized display!
