Yeah, there's also tablets like the Remarkable which claim to be hackable. I've thought of trying to build this myself.
With the right plugins maybe Anki wouldn't be too bad, still not as seamless as a dedicated device though. And I think this idea is important enough to warrant a dedicated device. Imagine how helpful it could be to have all students trained to use such a device to memorize their own notes. Memorization alone isn't enough, but it can serve as a foundation to build knowledge on top of. Many student lack any sort of foundation, and efficient memorization would do a lot for them.
Yes, memorization is one of the most important tools for learning. It greatly speeds up the process and sometimes is necessary in fields like medicine.
One problem I can immediately think of with a dedicated device is "vendor lock-in". Especially when you are going to spend a long time creating decks or practicing them, you wouldn't want to lose your progress or cards because some company stopped supporting their proprietary format.
This is actually the only reason I won't ever consider using most of these "Next Anki" or "Anki but better" SRS apps that pop up every now and then.
