By "heavy-duty", I meant a device strong enough so that its screen doesn't break while travelling. Like I said, I had the Pocketbook Tea 3 repaired twice… before giving up and getting the Bookeen Saga, which I've been happily carrying around for years now.

As for the PDFs I'd like to read on that smaller device, they're just simple one-column documents (with footnotes), nothing fancy. Just that they're not available in EPUB.

I'll read up on KOReader to see if it handles PDF better than the stock application and well enough on a non-Amazon 6" device so that I don't have to bother with the k2pdfopt step.

Stiil curious to understand what the "reflow" option in my Bookeen does under the hood with native PDFs — change the x,y coordinates dynamically so that text chunks are moved around to fit the smaller screen?
