@foone did you ever see the YotaPhone? It was a normal Android mobile on one side, but if you flipped it over the screen would mirror onto a very fast e-ink display.
@foone Honestly that would've been the move back then.
Low power consumption, MUCH better contrast, Actually visible in sunlight, about the same resolution, and the framerate on even the last couple generations could easily be done on eink.
And they didn't usually have password locks, so just drawing the messages to the screen as they arrived would've been so good for being able to peek at it without needing to actually do anything.
Honestly eink displays would be amazing for dumb phones. But even today's "dumb phones" are running a slim android backend with full navigation support and everything.
@foone I have a moaan inkpalm on order which is basically a cheap version of the boox palma... so, not really the same thing in that it's just a kind of slow shitty android device, lol.
@foone I have a tech fantasy about you building a computer with vacuum tubes and and using Pfleumer tape memory with a punch card interface and metal punched tape output .
