Best part is the terrific pixel density. The iPhone 5 and iPad Mini Retina both blow the eInk pixel density levels out of the water. I got rid of my pathetic PW2 because of its lousy lighted screen and fuzzy text. The iPad/iPhones are just so much better at rendering sharp text than any eInk device will ever be. The eInks are so LAST-DECADE in design, whereas retina screens are the latest technology for screens.
