When I clicked through, what I was hoping for was an e-ink tablet without the battery, where you have to hold it close to an inductive charging surface each time you flip the page.<p>Such a thing sounds stupid at first blush, but in combination with ubiquitous inductive charging mats (imagine them on e.g. every desk in an office), it could make for <i>extremely</i> cheap, thin and light e-ink devices—to the point that they start being more like documents than readers: flimsy laminated &#x27;paper&#x27; sheets that happen to be able to update themselves.<p>Heck, if you didn&#x27;t expect to use them outside of the installation (if they were for displaying internal manifests in a warehouse, or patient charts in a hospital, etc.) then you could externalize <i>all</i> the &quot;document reader&quot; electronics, and just make the device into a dumb framebuffer that hardware in the mat can push images to. (Though you might not <i>need</i> to do this; we can fit some pretty complex logic inside e.g. a credit card, so we might be able to fit all the storage+firmware chips for a full e-reader inside a piece of paper without that making it less piece-of-paper-y.)
