There are many alternatives to Active Directory, some even cross-platform. Microsoft basically has a monopoly in such things because those alternatives don’t work well on Windows (both OS and Server).

Even windows doesn’t run all windows applications, so I think it’s bad to judge that way. Hell, windows doesn’t even run itself properly half the time.

Well I would assume less powerful ones should take up less power. Also, don’t normal LED displays also require this, or sometimes more computation to calculate the pixels?

afaik it’s very possible to make e-inks with 20+fps, but the microcontroller used to power the display isn’t powerful enough. I’ll link the yt vid if I can find it.

it’s a 60 fps colour e-ink display
