Feedback Analysis is a method to write down what we expect a decision of ours will lead to, in 6–9 months or more. It helps review and compare actual outcomes with ideas and plans.
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.
