I believe our brains have a slightly different relationship to text on a page, because that page always has one specific location in the physical world. It will always be the same text, and on that same piece of paper. (Do you ever pick up a book and surprise yourself by remembering exactly where you left off -- that last sentence of the first paragraph at the top of the page on the right?) I think we're always subconsciously assessing where things are in relation to our current position, and that carries over to text on a page. But there's not the same permanence for text in an ebook. (Poof, it's gone! New text! There is no page, nothing has a location...) And yeah, sometimes that same "view port" can turn into an ad. Sometimes it's your book, sometimes it's Amazon selling you something. I just truly believe that you end up with a subtly different relationship to that body of text that you're trying to read and remember.
