Awkward delays arise, and repainting of the e-Ink screen sometimes lags. But, overall, the experience is quite good and, in some situations, noticeably better than using the previous iteration’s buttons. This is especially true of picking items from lists or selecting text in specific areas of the screen—touch, even on a screen that isn’t especially responsive, is simply much faster than navigating via repeated button presses.
Also this: “But if your focus is on reading, I would actually recommend the bottom of the line model. It’s lighter and more comfortable to hold in one hand, and the touch screen doesn’t really make the page turning experience that much better.”
