Is the response time really that fast? On my e-reader, it takes solid 1 second in the best case (and sometimes more than 3s worst) to switch a page. This device looks really fast. But maybe it's just updating small region and that's why it's so fast?
Just curious but which ereader do you have? The current higher-end Kindles (I have an Oasis and a Voyage) turn pages so fast as to be unnoticeable with a noticeable full screen flash every 10 or so pages.
Maybe it's just time for me to update? I bought this in 2014.
