[SonderDesign]

I'm the founder of Sonder, an E Ink smart keyboard startup; I've written here previously about E Ink when we were published in WSJ regarding Apple.

E Ink is a brilliant display, but the process of manufacturing, cutting the TFT mask etc is expensive; only on mass volumes can displays costs become incredibly cheap (6" E Ink in a kindle is <$10 USD). It's the same for most displays OLED etc in small volumes are expensive; which is why the touchbar solution COGS is over $200 USD.

Therefore E Ink has a high MOQ of a few hundred thousand units, anything below that and you're priced at basically prototype costs which is why a 32" E Ink display is $2k.
