I would love to see the performance trade-offs. I don't mind more battery draw, but how many shades of grey does it support? How bad is the ghosting? How white is the background? Is it clear enough to be used white-on-black? How often does it need a full screen refresh?

    Back in the days when OLED screens didn’t exist, the rule was that white on black text needs to be bolder for legibility. Since super high contrast is now par for the course, designers with high end devices forgot about this. I agree that the dark mode on the boox is terrible (I find for example obsidian absolutely unusable). But this could be easily fixed with bolder fonts.

  Answers would be more helpful if you answered based on the panel you were using rather than saying it depends on the panel

How long do the pixels last before they start getting stuck?

  I've had over half a dozen E-ink devices, and do not recall ever noticing a stuck pixel.

    In your sample size of 7+, do any of those devices refresh 75 times per second?
