When I first heard about ePaper prototypes becoming cheap enough and easy enough to produce that they'd make it into consumer electronics, I remember being shown these cool working examples of eBook readers and PDAs with rollable screens that would fit in your pocket.
Why do they still not have one? I seem to recall other companies making demo products along the same lines several years before the Polymer Vision one tomereader linked. Which, by the way, I still can't buy
I love my nook and all, but one of the promised benefits of ePaper was its ability to bend so I could have a 7 inch ebook reader that would fit easily in my pocket.
These future technology videos are fun to watch, but they're far too optimistic.
