The way I understand the technology : refresh time looks related to how many pixels you draw at once. When you write with a pen, very few pixels have to change state on a given unit of time (the pixels under the stylus) the "magic" behind fast writing on e-ink is to draw the pixels under the pen as fast as possible then if needed add details once the user stops writing.

The problem with your terminal is once you reach the bottom of the screen and you start scrolling : from now on, every new line will redraw the entire screen. Now you are exactly drawing as much pixels as any e-book which is … slow.

You would need a terminal without scrolling (or some mid-page scrolling). This could probably be done but you would probably have problems with a lot of cli programs.
