Barnes & Noble e-reader is dual-screen mess : This guy doesn’t care for e-ink in general, but he cares for the Nook’s dual-screen set-up even less.
The Nook tries to get around the slowness of e-ink by including a small, fast, touch-sensitive color screen below the main, 6-inch e-ink screen. While the main screen shows the text of a book, the small screen offers navigation options such as switching to another book.
This would have been a good idea if all the navigation took place on the color screen, but it doesn’t. That screen is too small, so the Nook uses the e-ink screen to display lists of books, clickable links and so forth. Not only does your eye constantly have to travel between the screens to figure out your options, you also have to wait for the e-ink to update. The setup effectively shackles the color screen to the millstone of e-ink, and our voices rise from the depths of gadget hell.
