I read somewhere that the e-ink expense is because the company which controls the intellectual property chooses to make it a low volume, high cost product. Not that it is inherently expensive, and I am surprised they don't try the opposite strategy, make it cheap and everywhere.

I've only read that here (repeatedly!) on HN and blogs that then cited throwaway HN posts which never respond to my requests for at least some verifiable evidence. Have a look through my comment history.
