I think it's more like it's like reMarkable Paper Pro but smaller.
The difference being the reMarkable Paper Pro not only has color + reading light on top of reMarkable 2, the writing experience as well as the stylus are different from the reMarkable 2.
* Phone-sized instead of tablet-sized
* Has color
* Has reading light
* Sensors detect when a folio is open or closed
Everything else is the same. Am I missing anything?
