I could definitely use a supplemental e-ink display, though I think that the touchpad is too small. E-ink works very well in well-lit environments, like outdoors in the sun, where LCD displays don’t do well.
I think that a more realistic route for laptops to have a supplemental eInk display is having the laptop have a protective cover that flips open and sticking a touch e-ink display on the back side of the laptop lid. Then you use the laptop as a tablet in that mode. I believe I recall seeing a smartphone manufacturer that did a dual LCD-eInk display on opposite sides of the phone.
Who wants this?

You can have a regular glass rectangle phone with both screens (of the same size, stacked) on the same side, bit easier than flipping it over
