I'm a big fan of pen-and-paper.
But years ago, on a Windows 8 Tablet, I copy/pasted my first handwritten note. That's when I knew that there's a huge future in the UI design of "paper-like" digital written notes.
Copy/paste. "Insert". Zoom. The digital landscape can make superior paper for thinking. It's still not as good as paper, but every year new devices come out and push the limits of UI / paper-like feel.
Eventually, someone will figure it out. Until then, tech-nerds will play with the toy and try to figure out how to make it better.
Artists have largely moved to digital ink / digital drawing styles. Its a bit odd that "thinkers" haven't found a computerized tool for "writing & thinking" yet.
Clearly, Remarkable (I never used this tablet before) is aiming at this niche. I'd probably give it a try, with a cautious degree of pessimism. I still haven't found anything as good as a $20 paper-notebook (Leuchtturm1917) and a $10 pencil (Pentel Kerry). But I await the day when some technology can replicate the experience.
