So I've spent the last decade trying to get to a decent note taking solution, through every iPad size iteration / pencil / paper-like screen covers, and also all the different eInk devices (Sony/SuperNote/Boox). My current flow, and the one I'm actually using day-day for the last six months or so is:
* Remarkable Paper Pro for note taking. It is a great device and there are a number of features that are just well thought through in terms of a paper substitute. It also has an app for desktop and also iPad that lets me synch and read (but not annotate) notes and PDFs. I had the other eInk devices, loaded them up with apps, but never actually used the apps as the experience is poor!...
* iPad Pro (smaller one) for wider content consumption (News+, Video) and the ability to read the Remarkable notes (so I have all my notes, I just can't write on them, useful when travelling on holiday). I really don't like the Apple Pencil for not taking (noise and friction, bloody thing always drops off the device), but can see for many wanting a single device how it works.
Looking at the new Remarkable, I immediately thought "that would be cool", but then realised it would still mean carrying 2 devices round with me, albeit lower weight.
