I would say that e-ink will stay around for reading, but there are critical differences between linear reading and textbook use. As far as textbooks are concerned, I would say that e-ink is a non-starter. The refresh rate is poor, navigation other than linear page-to-page progression through a single text is poor, annotation is poor, interactivity is non-existent, etc.

It's not a bad or doomed technology, it just isn't the right tool for this particular job.
