Direct sunlight being the key part of what I said; I've never had any other display that was so legible while sitting at the end of a dock with a blazing sun blasting straight down upon the screen.

Otherwise, for sure, in general conditions it was mediocre.

And yes, the whole project was sketchy as hell, in retrospect.

My Panic PlayDate, which lacks the paper-like contrast of e-ink but can refresh at 50 fps, looks fantastic in direct sunlight. I believe it’s using a Sharp Memory LCD.

So there is other tech for this.

But it's just black and white, right? Still, that sounds promising.

Yes, and the pixels can only be either black or white, not shades of grey. (Although dithering is surprisingly effective.)

My Pebble Time Smartwatch had a color memory LCD which was also easy to read in direct sunlight, but the PlayDate's screen looks a lot better.
