A good story always overcomes the limitations of the display device. However, there *are* some marginal works which benefit - maybe even greatly - from the enhancements of multiple fonts, styles and graphics. Plus, the author of the article completely ignores that as the e-ink medium advances, the levels of grayscale available will improve, the memory for storing of multiple font families will expand and we will even see color.
Of course, the breadth and depth of photographic art that was-and is being-created using solely black & white film and paper shows how lazy these designers have become.
