It's all too easy to dismiss the optimistic fantasies of yesterday: flying cars and robot servants may have filled the pages of Popular Mechanics in the 1950s, but today we're better grounded in reality, pinning our hopes on more reasonable futures based on technology we've actually developed. Still, even those predictions fall flat sometimes, and it can burn to look back at the track record of a horse we once bet on. For this editor, that stallion was known as color e-paper, a series of dimly hued electronic-paper technologies that teased a future of low-power gadgets with beautiful, sunlight-readable matte displays. Prototypes from half a dozen firms exhibited tantalizing potential for the last half of the 2000s, and then promptly vanished as the decade came to a close. Like many ill-conceived futurist predictions, expectations for this technology gently faded from the consumer hive mind.
The legacy of color e-paper may be muted and dim, but its past, at least, is black-and-white: monochrome E Ink set the tone for a decade of reflective, low-power displays. Years before the iPad and other tablets created the so-called third device, sunlight-readable E Ink screens nested into the public consciousness with Amazon's inaugural Kindle. Launched in 2007, it was a blocky, expensive and awkward device that had more potential than practical application, but the visibility of the Amazon brand lifted its stature. Consumers paid attention and the e-reader category was forged.
