Maybe one could plug in a little device to that with which to manage what appears on the screen, and when not in use -or during transport- keep the screen rolled up...
(Just fantasizing now... but a full size A4 reader -14"- would be bought by many. I would bring out a version with the simple basics, and then maybe special firmware apart for those who like whistles and bells. In the form of modules.)
