This stuff is cool and all, but I want a notebook that works like a notebook. You know, the paper kind that doesn't have a backlight. We've got screens you can write on, which are godawful expensive from what I've seen, but I'm pretty sure they all have a backlight, which uses up electricity. The world badly needs an ebook-type screen that you can write on as if it's notebook paper. And while we're at it, let's get it to work with all the content the thing can display. Maybe email someone a web page with some remarks scribbled in to the side. Yes, we can already do that, kind of, but writing with a mouse is a horrible experience.
