> A text heavy application where update rate matters is programming. And I would be the target audience for that.

I wish you get what you want soon. Nevertheless I would prefer there to be a cheaper option for those who only need to read static documents or watch dashboards of information which doesn't change fast.

> You can simply refresh eink displays with different methods that offer different trade offs

Needless to say eInk displays aren't meant to refresh the same way classic displays do. Only the regions which actually change are supposed to redraw. 1 Hz doesn't mean the whole panel is fully reset 60 times every minute, only that it takes a second to display a change. Is this what you mean?
