Kobo announces its first color e-readers

Both use E Ink’s latest Kaleido color screen technology, which has subtle, pastel-like hues and drops from a 300ppi grayscale resolution to 150ppi when you view content in color.

I had to check just how bad 150ppi would be when dropping down the resolution for color.

A 24" Full HD monitor has a PPI of 92. So it's actually okay.

I'm still using my old Kobo Aura HD (now roughly 11 years old) and the battery still lasts over a month. The screen was already decent back then, but a bit sluggish. I just checked, the old one has 265 ppi. Maybe it's not time for an upgrade yet :)

A PPI of 92, but that screen is going to probably be between 2 and 3 feet from your face, vs the 150 PPI sitting 6 inches to a foot away... Doesn't mean it isn't good enough by any means, but it's certainly not a conclusive comparison

I have a Boox Ultra C. It has the same screen, I can confidently say the colours are utter shite for any kind of colour sensitive work or media. However, they're more than good enough for conveying information, like different coloured lines on a chart.

The colours also look sharp as fuck, as the grey scale is still used for brightness, and the colour just tints it. Meaning it looks a lot sharper than 150ppi and almost indistinguishable from 300ppi

How is your boox, BTW? Would you recommend them?

I'm in the market and they look interesting to me but the price is a bit of a shocker

I would get a Galaxy Tab if the E-Ink isn't vital for you. But otherwise it's a very capable E-Int tablet, and it running Android means you can do anything on it you can an Android tablet.

The real killer is the latency though, for most things it's pretty bad, except in Boox's own apps where it's so damn quick it feels like writing on paper.

I wouldn't recommend it unless you know it's exactly what you're looking for, but if it is what you want then it's easily best in class

6 inches? I think you need glasses ...

[–] [email protected] 2 points 7 months ago

Yeah, 6 inches is about the furthest something can be for me to see it with any clarity at all without glasses, regardless of size and resolution, but still often read without them on my phone just to relax my eyes (and also, nothing looks clearer to me than something a few inches from my face with my glasses off)

But i did say "6 inches to a foot" which I'm at least assuming is not that atypical a range that people hold their devices at, but I'm not that great at judging distance overall... At the very least, my point is you're holding the small device much closer than the bigger screen will be so needs higher PPI to still look as crisp

[–] [email protected] 2 points 7 months ago (1 children)

Of course, but it's mostly for reading. The color will probably be used for notes and the occasional image, for which it's easily good enough. When I read it's usually a foot away, while I keep my monitor at 2 feet.

Black and white content (text) has 300 dpi atleast, so for that it's perfect.

E-Ink is fantastic for lots of reading and battery life, for everything else an actual screen is leagues ahead. The response time is awful too.

Fully agree, just an observation about the comparison
