If your primary use case is to read books off of Kindle, I'd say no, because Remarkable doesn't run on Android, and as such has no Kindle app. You can de-DRM Kindle books to read on it, but then you're adding these steps for no real gain.

If you're reading comics, then maybe, because this device is expensive precisely for the colored-e-ink screen. But even then better alternatives for that usecase probably exist, as the e-ink space is filled with Android based devices with better format compatibility.

Check out the Boox Palma 2. It has been an excellent Kindle replacement for me and is in the same smartphone form factor as the Paper Pro Move.
