On the other hand, for the same price as the 13.3" version and at the same size, I could print and frame approximately 80-100 photos, even from my gallery-quality inkjet - if I take the quality hit and use the HP AIO where the ink is free, that's about 200-250. (At that point it mainly depends on what kind of bulk rate I can get on the frames!)
So the unit economics don't really work out in favor of the ArtFrame here, I feel like. I wish they did!
I could assemble something myself, I guess, but I've got other projects taking up time and don't mind paying a little bit to turn the physical assembly problem (I'm bad at) into a mostly software problem (I'm mildly better at).
For reference: the 6" Inkplate costs around 100€ and I think you could fairly comfortably build a 10" EPDiy device at around that. That's without all the fanciness of course, with it I reckon it should be possible to sell these things at around 200€ each, which would probably make them a lot more interesting to people.
That said: I'm excited for color e-ink screens appearing on the market. The amount of devices released lets me hope at least some will make it to a secondary market.

EPDiy looks interesting, though.
Maybe it just needs a better lookup table or some preprocessing.
I’ve seen some impressive 1-bit displays, so 8 shades shouldn’t be harder than that.
Just buy some very cheaply-available electronic price tags [1] and use open-source firmware[2] which supports greyscale + yellow. Save literally HUNDREDS of dollars/euros/etc. For extra credit, they are not only black and white eInk screens, they are BWY, so they can add a splash of yellow!

And, separate question, but I tried just scanning [2] and I'm having trouble understanding how to determine the resolution of the tags in [1].
it is that easy - i wrote that article
bigger ones are rare but do exist
I know that most people assume that BWY and BWR screens cannot do greys, but that is wrong
On the https://framelabs.eu/en/technische-daten/ page both the 6″ and the 9.7″ is listed as being 222×309 mm, which is roughly the size of DIN A4.
On the https://framelabs.eu/en/artframes/ page, however, there's a clear difference in size between all models.
Could you check the sizes, please?
What do you mean? What specific type of display, what size of display, what volume and what is the price? I keep hearing this claim about "insanely expensive" , "patent troll" and every time I've asked simple questions like which patent, what lawsuits, what prices, I've never gotten a satisfactory reply. Please have a look at my comment history, I believe the prices of electrophoretic displays are directly linked to their volumes. The displays in use in high volume products are cheap while those hand kerfed large panels are a couple of orders of magnitude higher cost since their volumes a couple of orders of magnitude lower.
I also already asked in that thread for any form of substantiation and never got a reply. It is weird to see that exact specific comment linked to again and again. Boing boing linked to that comment, multiple blog posts linked to that comment and used it as a citation claiming E Ink is evil. Well, I don't know if they are or not, but something more concrete than a throwaway comment and a self-referential insane infinite loop of comments would be necessary for me to form an opinion.
