A few more impressions as I cross the halfway point of my first week:

99.8% certain that it will fully replace my paper journal: briefly returned to paper and went back to the reMarkable. Love writing in / on it: feels like a Papermate Flair / fountain pen mix without the waste of blowing through a box of Flairs a month. Lamy stylus supposed to arrive today. Have a feeling that that will clinch its victory.
Very nice to have gotten a handle on the touch gestures. Less friction = more brain.
A workflow is emergent.
Still haven't read anything on it. Or signed anything. Should have caught me a year ago, then it'd've been a different story.
The focus that writing on it instills transfers well to working on the Mac.
K was so fascinated by it that she bought her own for teaching. Have a feeling that it will be even more useful for her than for me (though it has already cemented its position as an essential brain extension in (what passes for) my creative practice).
My handwriting is and will remain shit but I learned to live with that long ago. In other words, text-type conversion isn’t in the cards and won’t be and I’m fine with that: I’ve been deciphering my scribbles since time immemorial and it’s not like I’m a doctor or anything important.
