As before, you can set the page refresh – that horribly intrusive white-to-black-to-white flash – to happen every page or every six pages. If you do it every sixth page there are some artefacts that build between flashes but it’s so much easier on the eyes that it’s definitely the way to go.
Or, like me, you might decide that artefacts building up on the page and a flash every six pages is more distracting that a flash every page which, frankly, you forget about. I always switch the setting to redraw the whole page every time. That's definitely the way to go.
I've been reading on e-readers for three or four years now - I don't even notice the flash on a page turn now.
But yes - I'd still like to have hard page-turn buttons.
