In essence: When you are reading your book in the morning in bright daylight you can close our book on page 300 0f 1200, and when you start reading in the evening when the light is low, you select a character size one notch biger you are suddenly on page 350 of 1400
So there is no real page number in an eBook. It is something that is left over from pBooks.
The only number that is fixed is the actual number of characters that you have read. And that is exactly what the position is...well devided bij 128 it is.
It seems to me that with a bit of forethought, an ebook could
display what page you're on, regardless of font size. All that would be required is for the format to have some kind of XML tag for the pages (e.g., <page1>, </page1>), using the pages of the paper version as a guide.
For books that don't start off as paper, I don't think page numbers make sense.
