Given the importance of color to branding I think e-ink is a nonstarter in it's current mass-produced form.

Colour e-ink is available for retail purchase, and the colour reproduction is passable. The refresh time is big fractions of a minute, but that's OK for static displays. Obviously that misses the entire point of this parasiteware, which is advertising and tracking.

That's a good point, and tbh I was aware of color e-ink but I assumed the price difference was enough to be a non-starter for a (parasiteware) company.

A screen+camera would actually enable insanely good insulation, compared to glass. A 4cm/1.6" PUR sheet weights next to nothing and has a thermal transmittance (aka u-value) of 0.4 W/(m²K). That's about twice as good as modern, triple glazed windows.

You could just apply a large poster on the front of the door. No need for a screen that generates heat.

But how does that sell ad space on my consumer attention spot market? And then they can't see the product they're about to buy! /s

The reliability issues are surprising: First on some testbench, developing software, power supply, (physical) install procedures, etc. With that done, one would expect to outfit a few stores to see how they work IRL. But no: "The initial round of installations in 2018 reached 10,300 screens in 700 stores." As part of a $200 million plan to cover 2,500 stores. From testbench to fitting 10k screens across 700 stores, w…

People often forget that when "moving fast and breaking things", some parts are more frangible than others.
