While pondering my masters thesis, the thought hit me that to go truly paperless (like some people are trying to do, see also the paperless challenge at http://www.studenttabletpc.com) it might be a good idea for tablet makers to think about adding an flexible roll-out e-ink type sheet on the side of your tablet. This way, it's possible to have your digital textbook or other digital source (web page?) next to you for easy viewing, while working on the main screen. Or did somebody already think of this? I know plenty of people work with 2 screens attached to a single pc, making this type of thing easy, but lugging a 19" flatpanel about might not exactly fall into the 'mobile-solutions' category.... Any thoughts or suggestions? Could this work?
