I think the person you are responding to is not thinking visually. They basically seem (to me) to think reformat-flowed fixes this, and that having the view of a web page alter because you open a book, is "not a bad thing" when you (and I) are of the view, if you maintain the aspect ratio and simply decimate how many pixels are available to show it, the actual "change" in the layout is kept to a minimum WHICH IS THE INHERENT GOOD HERE -the whole point of the A, B and C series is that the scaling function preserves the ratio of sizes of the contents, under the quality change of bigger or smaller fidelity of presentation.

Unless there is some upsight I am missing, I think the OP just "doesn't get it"
