(19)The portable, paperless e-newspapers would be a huge environmental win, eliminating the need to cut down trees and burn gasoline delivering the traditional folded parcels to readers’ driveways. Like many technologies, however, e-paper has been slow to take off.(20)In the past year, since Amazon introduced its Kindle electronic reading device, thousands of Americans have experienced the pleasure of e-books—but for most people, e-newspapers aren’t yet a reality. Millions of us already read paperless newspapers and magazines on the Web, but e-newspapers would offer different benefits for both readers and publishers. For consumers who already spend too many hours staring at PC screens, e-newspapers would offer portability and a simple reading environment, free from e-mail bells ringing or Instant Messages popping up in mid paragraph. Among publishers, there’s real hope readers will pay subscription fees for those benefits, and that advertisers will pay considerably more for ads on e-readers than they do on the Web. For a primitive look at how e-newspapers might work, consider the Kindle. Amazon currently offers 24 newspapers for use on the device. Subscribers pay $5. 99 to $14. 99 per month, and each issue arrives wirelessly before sunrise. However, e-reader enthusiasts describe reading a newspaper on the Kindle as disappointing.(21)The Kindle’s black and white screen doesn’t handle photographs or graphics well, and its e-papers carry no advertising. Instead of offering well-designed pages that entice readers to skim a story they might otherwise skip, today’s e-newspapers merely list headlines or tops of articles, which makes it hard to decide what’s worth reading.
