The image doesn't do service to these displays which are actually high resolution/high contrast. The other key pluses are you only need power when the image changes and you don't need backlighting - so potentially very low power consumption. The downside is it still takes over half a second to change a pixel. I'd love to see a general purpose computer with this display. Presumably other people have judged it is not acceptable to users but the promise of something that runs off solar cells is very seductive.
