That depends on the environment. Natural light fights against the functioning of light-emitting displays. Reflective displays cooperate with natural light.
You in the dark? Use OLED. Under the sun? Use EPD.
I don't know too many people operating desktop computers under the sun. They are usually situated indoors, often distant from any window access. Anyways the point stands that additional lighting discounts any power savings from using e-ink in a desktop environment. I get the use case for e-ink in the field. This product is not for in-field use.
HN is nth standard deviation sensitive. There is always market for some.
> additional lighting discounts any power savings
Not necessarily. Lighting today can cost fractions of watts, and on the other hands EPD can be energy costly - it depends on how many cell updates you are causing. So, the matter is probably less with energy consumption, and more about getting a better effect based on user and environment.

Sure, it does not seem specific. But it can have its places. Be it some production site - maybe a quarry near the tropics -, be it personal - maybe you want to do some work in your garden...
