Nope...don't use kindle...just Marvin. And when you say "you get a
sense of how much you've read and how much you have left" then you are saying that an exact number isn't really necessary. One is only better because you prefer it that way. That's fine too...but I find it very unbelievable when you make claims like "most people want page numbers" without posting some references.
And just because an ADE device is not in my recent usage list, does not mean I don't have a brain in my head. I'm old enough to have read enough text books and pBooks to be familiar with the concept thank you very much...
...and when reading pBooks I still never cared about what page I was on or exactly how many pages were left...I could see at a glance how far I'd read compared with how far I had to go by comparing the thickness of the two sides of the book - just like the progress bar shows how much I've read vs. how much I have to go in Marvin.
