How's the battery usage? You mentioned that it's not bistable and doesn't retain an image on power-off; does that mean the display requires non-trivial power even while displaying a static image? One of the big selling points of my reMarkable 2 is the incredible battery life.
Any plans for color? I know it'd be a sacrifice of brightness. I'm still interested despite the limitations.
These types of displays use power to change the pixels, but almost nothing to retain the existing image, so battery life will be wildly variable depending on how you're using it. Browsing the web with nonstop animations versus reading a book will probably show massive swings in battery life.
It's not e-ink, but it appears to be the same as Sharps "memory" display, which means it continues to show an image even after power is removed. They have extremely low power draw when displaying static pixels
