A notebook feature in an e-reader is a GREAT idea. A definite boon for students that would turn e-readers into must-have items for students. Particularly if that notebook feature was customizeable...for example, able to turn the e-reader into a small whiteboard. Imagine how useful that would be for people who lose their ability to speak. My mother has motor neuron disease and must carry around a small whiteboard in her purse to write on when she wants to communicate. I'd love to give her something like an e-reader to make communication easier for her.
