ePaper

So called ePaper products have been in the labs for years, but Sony's eReader is ready to launch.

It is 9 ounces (255g), the size of a paperback and its flicker-free screen actually looks like a printed page. It has ink particles suspended in liquid moved around by electric charges; a sort of Etch-a-Sketch on steroids.

Senior Vice-President at Sony Electronics, Ron Hawkins says: "When you form this image each time you're not using any power to refresh the image, even when it's not changing. So you have very low power consumption.

And you can actually read on our product about 7,500 pages on a single battery charge."
