Maybe eventually. But ePaper isn't a great display for an interactive UI. The screen refresh rate according to the specs is 3s, though I assume that partial updates (only repainting part of the screen) is faster.

ePaper makes more sense for use cases where the display is mostly static (e.g. Kohl's started using them as updatable price displays; doesn't matter if it takes 3-5s to write an update when it's once a week or whatever). Also because they consume zero power while static.
