Some people don't care, and I do not begrudge their enjoyment of colour cover art. I also would never buy a Kaleido device, as I need high contrast to avoid eye strain when I read.

If E-Ink were spending money trying to solve that problem, I think you'd see a lot more positivity surrounding colour devices, because ACEP can offer colour without compromising the quality of BW content the way Kaleido does. Unfortunately, Kaleido is a cheap and easy approach, so it's popular right now, and that's a bad thing, because it gives E-Ink a reason not to work on proper colour e-paper technology.  |
I'm sure E ink Corp has done its best.
ACeP was first demoed nearly 8 years ago. It's older than kaleido.
It's in reality tragically slow, maybe worse than the 1.5 second refresh, which is TEN TIMES slower than regular eink.
The faster Regal mode invented with Carta (not on Pearl) nearly 12 years ago can maybe do only about 8 shades/colours or less at 150 dpi as it doesn't do the greys. A full tone mono image is much slower to change on any Carta model.
I'd not hold my breath for faster ACeP even should Apple and Nvida and Amazon jointly fund it.
