Besides the demonstration using video, in my view the important point is that E-Ink technology is reaching refresh rates that make it usable for the display of a laptop. Think about a PC that, by not using power when displaying fixed images and by putting the processor in near-sleep every time it can, has a battery life of (say) 50 hours with common batteries (just think about how much of your screen displays a fixed image, and for which fraction of the time, while you're using the PC... the ability to perform partial refresh is of course crucial here).
Moreover, such a PC:
- could be used in full sunlight or with strong ambient light;
- would perform greatly as an ebook reader.
Can the lack of color make such a device unmarketable? Let's hope not.
