I know, and quality of photographic reproduction is not a criterion I would need from an eink display. My goal is subtlety. Honestly in a parallel universe I have probably built the same exact prototypes from the blog. My (defunct) startup was called Nitrogen Logic because technology should be as critical but invisible as the nitrogen in the air. I am totally fine with an 8:1 contrast ratio if it gives me perfect integration into the ambient light :) Photography would be displayed elsewhere, in a place that is meant to draw attention. I want eink because it shouldn't grab attention at all.
