The 10.3″ is too big to read novels. A 7″ is a good size for people that want bigger than 6″. A Sage is good for notes (better than 10.3" I think), but a tablet with digitiser is better. The Sage is also more expensive. It seems crazy to discontinue the B&W Libra (Libra 2) as the Libra Colour is a lot worse for people that read novels, which is the main reason to get an eink. My collection of PD novels was less than 100 in the 15 years of downloading them before I got eink. Now I have over 6000 PD novels and 600 bought ebooks over the last 11 years since getting eink. I read several novels a week. If I was a more occasional reader I'd just use the phone now (6″ plus with 512G storage vs 3.5" with a few 100 MBytes nearly 20 years ago). |

Also the Kobo is absolute best for subtitle, collections, series and exporting annotations with Calibre management.
Android isn't great, but Android on eink seems worse. I've had or tested 8 models of Kindle. I still have 3. I'd never go back to Kindle eink. If deDRM fails and an ebook I want is only on Amazon, I'd sooner read it on a Kindle App than get I Kindle. I nearly got a Scribe for PDFs, but when I realised Amazon only wants you to have KFX versions of PDFs I abandoned that idea. Nebo on an Android Tablet is better. I'd used a reMarkable and also an Elipsa. I could easily afford a Libra Colour, but I can't see the point of it. |

I think this has to be a supply issue, my guess would be that Kobo was not able to source enough 7-inch Carta 1300 panels for the expected demand. It makes no doubt in my mind that when this is sorted out they will release a new Libra BW. |

If Kobo finally releases that b/w Libra (and unlike you I'm not at all sure they will), the whining and grumbling will die down, I expect. |

I suspect there would be much less negativity if Gallery 3 were on the rise, instead of Kaleido. ACEP uses a better approach that involves white, cyan, magenta, and yellow cells to form colour, much as a printer does. This avoids all the problems Kaleido brings to the table, but it has one major downside, and that's an abysmally slow refresh speed. 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. |

Kaleido uses a 2 x 2 pattern and the dots don't cover the pixels, so 1/2 resolution both ways and not as dark. Still not usable indoors without a front LED light most of the time, so you might as well use LCD and a backlight. It's from 2019, so now five years old. Both have a theoretical 4096 shades/colours, but because the kaleido is pastel and there are really only 14 in between levels as well as black and white, the real usable range is much less. Really poor for anything other than comics that simulate 1930s limited colour range on wood pulp paper. Because of the coloured dots in the pixels the 300 dpi mono mode has not the sharpness of ANY 300 dpi mono panel and suffers two kinds of artefacts, the "screen door effect" and if a mono pattern aligns on pixels of one colour or misses pixels of one colour you get coioured patterns. The panels could be driven at only 150 dpi for mono and that would be avoided. Quote:

ACeP is a completely different kind of eink that's subtractive, so inherently no resolution is lost and and it could be in theory brighter. Sadly it's x10 to x20 too slow for an ereader and may not be very high resolution. It's from 2016 so now nearly EIGHT years old. Triton was abandoned years agg in favour of Kaleido, which is "better" on average if you don't mind worse colours. Both are simply printed patterns on regular mono eink. The light pipe layer is next. Kaleido has been gradually tweaked. It won't get better, that's physics. It's taken them years to produce volume of ACeP and anyone that uses it to build an ereader is clueless. One company at least tried. It's only good for signs. The big growth of eink isn't ereaders, or even Kaleido ereaders, but supermarket price labels, often using the red / black / white eink. They are lower resolution than ereaders, so likely better yield. The larger A5 size panels look like Pearl displays. The ACeP can only compete for signage where power is an issue or sunlight. LCD, OLED and now 5x brighter QLED (really LCD with quantum dots and blue LED backlight) are winning. Kaleido is a desperate ploy by smaller ereader makers to carve a niche. There is a bigger more secure niche for mono eink. The coiour eink based on Kaleido is a dead end and it doesn't look like ACeP will ever suit ereaders. The great thing about mono eink with the front light off is that the "colour temperature" of the panel perfectly matches ambient because it's 100% reflected ambient light. Kaleido can't do that. A decent matt surface oled or lcd will beat Kaleido if the brightness is properly adjusted and is nearly as good as mono eink with the front light off. It's just as good or better when you have to use the eink front light due to lack of ambient light (power cut or camping). Battery used to be an issue for phones / tablets but isn't so much now, especually wiith "power banks". I was looking at designing a product using eink in 2007. I played with a Sony eInk in Ireland a year before the Kindle was released. We had great hopes for the Qualcomm Mirasol, invented in 2004, by 2007. By 2012 it was dead. One model of ereader sold by two brands in China that didn't live up to Qualcomm hype. The future of colour isn't even OLED, it's "Crystal LED" (real LEDs, the OLED are electroluminescent dots with phosphors) and QLED (green and red emitting quantum dots powered by blue light on an LCD). I got a matt OLED phone just today and it beats my 5″ and 4.7″ eink ereaders for paper like quality, but I'll stick with the 8″ Sage for regular novels. |

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. |
