yeah the book idea is perhaps a little bit to expensive but perhaps the same thing with a newspaper, so you have your NY times that has the same format and around the same number of pages every day, you buy a year subscribtion on it and you get a paperdisplay-newspaper that will be updated every morning with new information. That would be pretty cool.
