ebook

"The [ebook] Reader employs a new display technology from a company called E Ink. Sandwiched between layers of plastic film are millions of transparent, nearly microscopic liquid-filled spheres. White and black particles float inside them, as though inside the world’s tiniest snow globes. Depending on how the electrical charge is applied to the plastic film, either the black or white particles rise to the top of the little spheres, forming crisp patterns of black and white.

Once those microspheres have formed the image of a page, they stay put without consuming any power. Amazingly enough, that means that you don’t have to turn the Reader off, ever. When you’re done for the night, just lay it on your bedside table; the current page remains on the screen without draining any battery power. (According to Sony, one prototype Reader in Japan has been displaying the same page for three years on a single charge.) Every instinct in your body will scream against leaving it turned on all the time, but you’ll get over it."
