E Ink in white state is white at the top, while transflective LCDs display black and white by blocking or allowing reflections at the other end to go back up layers of polarizers. I'd guess that that difference makes E Ink significantly superior to LCDs. This is totally "old man's why it can't be done" hallucination, though.
