My conclusion is that reMarkable team delivers on their promise, to create a true paper tablet. The device delivers better paper and has replaced my Leuchtturm journal. I use more digital paper than I ever used offline paper, I no longer refrain from getting a "dead" copy as a PDF to draw, doodle and ponder upon. It is a reMarkable device, yet with some quirks to overcome, which are all entirely possible with future software updates, which have been promised to come "soon".
I have finally received my reMarkable after waiting since summer, and used it for about a week now. I have used up about half of my first nib, need to charge the paper tablet daily and it has completely replaced my Leuchtturm and Lamy for keeping my daily journal.
