More on digital books

Following the launch of the Sony Reader, here's more on why some people see a bright future for digital books, from Business Week.

Portable devices are becoming lighter and more appealing. Books are being scanned into digital form by the thousands. The most important step forward may be in "digital ink," the technology used for displaying letters on a screen. A small company called E Ink has created a method for arranging tiny black and white capsules into words and images with an electronic charge. Because no power is used unless the reader changes the page, devices with the technology could go as long as 20 books between battery charges. The text also looks just as sharp as ink on a printed page, since each capsule is the size and pigment of a grain of laser-jet toner.
