Just fixed the Mobius Carta naming scheme.

I see you have listed the Nook Glowlight 3 as "available" but these have been discontinued for a couple (maybe three years now). I doubt that Barnes & Noble will ever get them back in stock (even though they still have them listed).

You're welcome! Have now listed the Glowlight 3 as discontinued. Thought it was just out of stock as the page was still up at Barnes & Noble (whereas the pages for other discontinued models have been completely removed), but if it's been out of stock for years then it's probably actually discontinued.

The Kindle 2 also upgraded its memory (even in the non-3G version) to 4 GB instead of 2 GB. So it's the same kind of thing as the Kobo Mini (unannounced) upgrade.

Interesting. Will look into this, and think about how to best list it.

Fair point, will look into that. I left it out for some devices as it makes the 'Name' column wider, and I don't want that to take up too much space (especially on mobile). But It looks like I can fit 'Ratta' without widening the column.

Thanks, will have a look! And yes, I'm trying to include a lot of discontinued devices as well, as people will often want to compare what they currently have to newer devices to see what kind of upgrade they'd be getting. Also, there seems to be a quite active second hand market for some of these devices as well (and I'll be adding Ebay links for every discontinued device soon).
And annoyingly, most brands and retailers completely remove pages with information on their old/discontinued devices, so information is sparse. So compiling all of that info in my comparison table will hopefully address that issue. Have already done quite some 'internet archeology' to fill in some of the info.

That's what I thought at first, but there seem to be a few exceptions to that: Lenovo Smart Paper is listed as having "Carta HD" but it's got a 227 PPI. Also the Nook Glowlight 4e is said to have a "Carta HD" screen, but it's only got a 212 PPI. The Nook Glowlight 4e also has a lower resolution than what is usually referred to as a 'HD' resolution (anything over 1280x720), as the resolution for the Nook Glowlight 4e is only 758x1024.

Wikipedia (https://en.wikipedia.org/wiki/E_Ink) says this about Carta HD: "E Ink Carta HD features a 1080 by 1440 resolution on a 6" screen with 300 ppi.", and list it as if it's a separate technology somehow. But that also doesn't seem consistent, as there are also larger e-readers with a larger screen that say they've got a Carta HD screen (Meebook P78 Pro, Lenovo Smart Paper, Boox Nova Pro).

Then there's also the mystery of what constitutes "Carta Plus", but only Onyx Boox seems to mention that type though.
