Much depends on the reader software. On the ones that I usually use I turn off the progress bar. I don’t like the “page” cluttered with extraneous stuff. Of course, I can, and do, check it when I want to see how much is left.
But looking at the progress bar is not the same cognitive process as feeling the heft of the remaining pages in your hand. The latter is subliminal, pervading your understanding of where you are in the book as you read.
I note the same disorientation in my “progress” through the story that I feel in an ebook as I do with collections of stories bound in same volume. I don’t get that sense in a physical novel.
[Ed: added “software” for clarity.]
