Haven't been using it as much but the builtin Pocket integration is also really convenient & slick for reading articles.

The Kobo also has a fantastic aftermarket world of open source software. https://github.com/topics/kobo?o=desc&s=updated

For a while folks were starting to get their own regular distros running on Kobos too but I'm not seeing much follow-through.

The reMarkable probably has an edge in overall open source tooling. They definitely have a much better page showing off what's available, https://github.com/reHackable/awesome-remarkable.

But Kobo is quite impressive & flexible. Great out of box & hackable ecosystem. Prices are reasonable, the base software is pretty great, and as you say, software updates just keep coming. I was running an ancient but lovely Kobo Aura HD until a year or so back, a fairly ancient device, & was still getting updates, getting faster/snappier & ever improving navigation/UI. My newer cheaper device has been great. Kobo has been such an excellent company to their users; it's been, ah, "remarkable" to see.
