Amazon reveals first color Kindle, new Kindle Scribe, and more

Using the wisdom of the crowd here: what is the best ereader for tinkering? I'm browsing the answers here looking for that and I don't know if anything actually fits the bill. Something with Android, tablet-type machines, seems to be the answer? Is there nothing better?

Get a Kobo, which model depends on your needs. A Kindle is never yours since Amazon can push arbitrary updates wipe your stuff. Don't buy Boox either, as they include a lot of bloatware, not to mention they're blatantly disregarding GPL.

Kobos are mostly just arm linux machines. You can install KOReader on them for a better reading experience.

Inkplate probably

I’ve read this, but I’ve also heard various downsides to Kobo, including in the discussion on this post. (Battery issues, general device glitches, etc)

Which Kobo do you use, and how has your experience been?

Specifically if you want android then boox something.

Kobo you can put custom scripts on to run stuff like koreader which is nice.

Libra H2O. Never had noticeable issues I'd say. Battery life is quite long. I couldn't get syncthing to work reliably, though it isn't super necessary.

depends of what you means by tinkering. The pinenote maybe ? https://pine64.org/devices/pinenote/

Remarkable is very tinkerable[1]. I've had a lot of fun hacking mine! It could be better, but all in all, very good.

Is the Pine Note finally purchasable? Every time I've tried, it's not available.

Look into PocketBook readers. They have a full lineup with color and grayscale in various sizes. They run linux, you can ssh into it and install koreader, etc. They have a good privacy story and little vendor lock-in. The experience is a lot like my Kobo, but the matching mobile app is much better. I continue where I leave off with my iPad sometimes, it's a nice feature.

FWIW I've been running a jailbroken PW5 for a few years now always connected to the internet without any issues dealing with updates.

I did rename the ota binary. I'm aware that there's always the possibility of Amazon maybe having some other way to push an update, but I haven't had any issues so far.

Depends on what you mean by "tinkering". I had been on the lookout for a large Ereader from the very early days (i love reading books) and had owned a IRex Iliad and Nexus 10. I was looking for at least an A4 size screen (a must for reading technical papers/books) and finally settled on the Samsung Galaxy Tab S9 Ultra (14.6 inch screen) which i bought this year. I have the Moon Reader Pro+ as my ereader app and with the S Pen you have note-taking capabilities too. Add a bluetooth keyboard/mouse and you have a easy to carry "laptop/tablet/note-taking ereader" for many usecases.

ReMarkable is somewhat tinkerable, it's a shame that (for the RM2/RM3) drawing the screen requires DMAing into memory that's owned by a proprietary blob and moves every update.

reMarkable (Linux) or PineNote (Android stock, or Linux)

Good for you, but you can't count on buying a new device and having it be jailbreakable. For someone deciding what to buy it's not a good option. It's also a lot of work and worrying over something you bought and paid for.
