According to the Times, Asus will release two models, with the lowest priced at about 100 pounds. It isn't clear if Asus will link the technology to a publishing distribution system or to other content --- the Kindle is, of course, an extension of Amazon.com and has deals with several print organizations.
But what is a major development is the format of the Asus unit: full-colour and hinged to emulate the reading experience. One of those two screens can be used as a keyboard.
With Sony readying a new unit at less than $200, and Plastic Logic in the wings, the race is going to heat up in the months to come. Still, recent research from Forrester indicates mass appeal depends very much on a much lower price point, no more than $100 and as little as $50.
