The Onyx Boox Tab Ultra C has received favourable reviews from many e-ink youtubers. But the reason at least partly seems to be that it has a dedicated GPU to reduce ghosting. It uses a lot of resources just to be usable.
And even then the drawbacks are clear to see: subdued colours and a really dark screen - it needs the frontlight at 50% in indoor conditions just to be usable. And the battery drain seems to be massive.
I don't see how Amazon could utilize this technology with the hardware they use for the Scribe, for instance. There'd be too much ghosting and the screen would be too dark.
Maybe they'll do it in 10 years if there's a usable Gallery 3 technology by then.
