I thought I wanted one of these e-ink based devices for sketching or notes, but it turned out that I actually wanted a Boogie Board. [0] The eInk-based notepaper has been a long time in coming and you don't even get good latency, while reflex LCD, which the Boogie Board uses, is instant.

You're comparing two different things. Boogie board is not a display panel with a matrix that can be controlled electronically by software. There's no "pixels", which is why you can't use software to write to it or change the state of individual pixels. The cholesteric LCD being drawn on in boogie board is similar to the surface material in an etch-a-sketch.

Woah damn that is some ugly product design

who are they targetting, toddlers?

if you look at the clear one it's shown with a set of flash cards for tracing letters, so maybe not toddlers but young.
