I have them all (e-ink, tablets and smartphones) and use them all but for reading regular books, my Kindle PW is my go to device. It's smaller, lighter weight, and is optimized for the best reading experience for me. I suspect that most avid readers prefer e-ink although a general purpose tablet suits a wider range of people because it's a multi-purpose device, where as e-ink readers are niche devices, designed to do one thing only, read books, but to provide the best possible reading experience.

I've never seen detailed statistics but suspect that Amazon and other e-book sellers would find that of their customers who buy more than 3 to 5 e-books a week, the majority own and read them on e-ink devices. These customers are by far their best e-book customers and a major source of revenue.

I can't imagine that Amazon, in particular, would ever stop making e-ink Kindles unless a better technology emerges. I'd go back to reading paperbacks before switching over to a tablet for my reading.
