I just don't understand. In what other product category do we see barely any finished products and mostly just working prototypes without housing, etc. like in this video?
Sure, this technology is new and expensive, but so are foldable phones, for example.
I guess a major indicator of progress in this market will be Amazon releasing a colour kindle (if they even want to bother), as that will both indicate prices and performance has become "good enough", and be a further driver on both.
Until then, a $2200 32" screen with a 2-second refresh time is a curiosity more than a product. I think, so far, epaper/eink has hit some sort of wall with it not having quite as many use-cases as people assumed.
