This is nice for people who want it, and it might be better for reading on phones (but that will require testing to confirm.) For reading on a large enough display (laptop, desktop or even any newer tablet), I think it's unnecessary. The way I read on these devices doesn't involve scrolling very often. I read like I do on print, but scrolling replaces the page turn much like it does on his. I don't read text while I'm scrolling usually, I'll read what's on the page, then scroll it to give me a new chunk to read. It's not a big deal at all.
