> [W]e need modern, digitally-native documents that are as rich as the information they contain. It's best to separate interactive parts from the non interactive. When I read papers I always print them because I can take notes, underline, draw shapes, comment etc. all in-line with a pen that I'll buy from a closest little shop if I don't have one with me. It is more convenient that any software tool out there, because there is basically no limitation to how I'll use the pen on the (actual) paper. But how will I be able to print a video, or a graphic that has some controls to be fiddled with? But they can be provided separately, and if I have the mediums, I'll use also them.
