Is this true 3200x1800, or only one primary (R, G, or B) per pixel? If memory serves me right, the last desktop color e-ink panel we saw was the latter, making it effectively 1600x900 RGGB (or RGGB/BRRG/GBBR if the greens weren't twice as common). There is then also, of course, the inanity of the choice of 16:9 when the mold is already being broken by the novelty of the technology.

Still neat from a technical achievement point of view.
