Basic physics
1) It can't easily be used without a front light in normal light good enough for mono eink without front light or paper.
2) The pattern of coloured dots mean certain fonts and mono images will have artefacts.
3) The colour is 150 dpi and the mono can't be a true 300 dpi due to the coloured printed dots.
4) The dots don't cover the pixels so as to allow better brightness, and make mono seem a little sharper than 150 dpi. This means only pastel shades.
5) Eink only has 14 levels between fully black and white. This means colours are really poor.
6) Because it's a 2 x 2 pattern and not RGB stripes on 1/3rd width pixels the processing, thus power consumption to do colour refreshes is increased.
7) High speed refresh (less shades) isn't compatible with colour use, so colour refresh is as slow as the slowest grey scale images for any sort of coloured content with more than 8 basic shades.

This isn't new. It's 3 year old that could have been done 12 years ago. It's a marketing fad.

I won't waste my money on it. An emperor with very few clothes. It's poor colour and contrast and hugely (night & day) degrades reading actual novels. If Gallery was about x20 faster it might be viable, but Kaleido will go the way of Triton or "kill" eink if there are not decent mono markets.

Kobo, by all means sell your Libra colour, but what stupidity led you to have no 7″ mono model? Why end the Libra 2?

I'll stick to mono Libra and Sage for ebooks. I'll use better solutions when I really need colour.
You're obviously free to buy what you wish and leave the others on the shelf.
Most of your assertions are sketchy, but your assertion that the difference is night and day is demonstrably untrue.

I have exactly ZERO problems reading with my Libra Color. I don't find that the experience of reading novels is degraded at all. Not even a little.
