I have added the older Ratta Supernote A5 and A6 Agile to the table, and started adding Bigme e-readers as well (not done yet).
If you're missing any other devices, let me know! I'm looking to add as much as possible so you can compare practically any e-reader/e-note/e-ink tablet.

The original Carta may have been renamed.
Pearl was the biggest incremental change and original Carta the 2nd biggest. Mobius is now of little value as the readers use ribbed rear flat front alloy plates for the screen. Some ereaders had a cutout for the LiPoly cell (battery) and then when it swelled the screen substrate cracked, such as Story Cover.
The mobius was intended for large screens where the ereader might flex. Likely the yield and lifetime is lower, as that's the case with flexible OLED.

Thanks for the info. As far as I know the original Carta was renamed to 'Carta 1000' but nobody really uses that term. Apparently there's also Carta 1100 but I haven't found any devices using that. Still not sure what Carta HD is supposed to mean (another thought that came up was that it could be a synonym for Carta 1100, but can't find any evidence for that, so probably not).

I run a Swedish forum about e-readers and one of the most common question is which e-reader to get which can be used standalone.
Having information about support for Adobe-drm reading, Adobe-drm full (i.e. acsm -> epub), Overdrive and Readium LCP would be very useful, I think.
Also, streaming services (like Storytel) are getting more and more popular. Which readers support all those apps would also be nice, although I guess "Android" could be indicator enough. (Most apps work surprisingly well in newer Android (Onyx), not so well in older versions.)

You're welcome! And I was already considering making a more detailed list for software and file-type support, and will likely do so in the future. Will be a bit of a puzzle on how to best implement that without making the table way bigger than it already is.

Converesly System A TV, 405 lines, was about equivalent to about 320 x 377 and was HD in 1935, because 6" to 9" 5:4 screens using round tubes were common and it replaces 22 line to 180 line mechanical systems.
The USA 525 lines (VGA based on it so 640 x 480) was designed to be roughly equivalent to 16mm film. The 35mm is about x4 resolution in 1940s but was used (is still occasionally) with much larger screens and modern film stock needs scanned at about 8K to give post processing UHD (4K). Some cheaper BD is simply the 2K HD scan used as master for SD DVD instead of re-scanning at 4K.
HD has become slightly meaningless and HD Ready was always a marketing scam.

Just looked into it, and yeah, HD can basically mean anything. Oh well. Still not sure what 'Carta HD' is, but I've just listed it if in the table if the manufacturer does for now.

Thank you! Yes, took a ton of time to make this!
