What resolution are we talking about then?

Guess I should comment again on this. Their data sheet
here claims outright a 3072x600 resolution in black and white mode, and able to be utilized via:

This increased resolution can be effectively used with sub-pixel rendering and with MPG, JPG, and TV compression schemes which use 3-4X higher luminance channel resolution compared with chrominance channel resolution. This display can support such an encoding scheme with 3X higher resolution in luminance than in chrominance (e.g. color).

The result for text will be something like 350ppi horizontal resolution, and around 120ppi vertical, assuming subpixel rendering is used effectively. Imagine if they had a 1366x768 panel to work with. That would be pretty impressive.
I would like to get my hands on a screen and take a closeup of the pixels to see the real-world results, and compare it with EPD. Would love to add it to my mosaic of text closeups (below).
