Thumbs down for Remarkable. Dumb vendor lock-in with subscription fees and inability to easily transfer notes, no external app support, yet still retails close to iPad prices.
At that point, deploying locked down iPads is easier, cheaper, and offers more flexibility. Which is exactly what a lot of schools and universities already do.
I owned a Remarkable and returned it because it is so frustrating.
Remarkable runs a scuffed version of Linux, which requires developers to release a separate version of whatever app they have. Although the selection is growing, it is paltry compared to offerings from a typical Android or iOS device.
Below is a list of so called “best” apps. No syncthing, no Obsidian, no Saber, etc. Multiple scuffed versions of Zotero that can’t do annotations.

Even for the few custom apps available, these are all uninstalled and reset with every OS update.

If you don’t want to use the few third party cloud sync options, then Remarkable charges money for cloud sync.

Remarkable’s notes are also stored in a proprietary format that cannot be read by other applications. Attempts to reverse engineer it are jank af.

It it works for you, great 👍. But I cannot whole heartedly recommend it. Even if you love eInk, just grab an Android based one like Boox.
