I had a CrossPad twenty years ago. And it feels like this device has improved extremely little from it. The CrossPad was recording what you wrote in a notepad placed on top of it, it had a little radio in the pen, and later you could download what you did, if I remember, in a vector format so it was better than a scanner. The ReMarkable on the other hand, records what you are writing on a screen and later you can download what you did because it seems the device is not capable of doing a thing with it.
In twenty years, we got... nowhere. Now you can wipe the writing surface with a button press instead of turning a page. Twenty. years.
