The last year or so, a few products integrating a Smartphone with eInk screens has been announced. Few have come to market and none are successful yet. Personally, I'm very interested in the idea, one less device to keep track of (not that I would dispose of my eReaders). The latest is Alcatel One Hero, that has some magnetic connector which allows an eInk screen cover to be attached.

If we try to look at this strictly from an eBook reader's perspective, why hasn't this taken off? What is lacking? Does it need to be built in to the phone? Lack of OS support in Android/iOS (not driving two screens at the same time)?

If you were to buy a phone with eInk support, what would you require from the phone? Size? CPU? Memory? Separate eReaders can now be obtained for around $50, if an add on eInk screen to a phone costs $100 would that be a dealbraker, or would convenience carry the day?
