Same, I already had a reMarkable tablet and got the reMarkable Paper Pro Move as an impulse purchase (ignoring its ridiculously high price) expecting to return it within the 50-day return window, but the fact that it fits in my pocket (or “most of my pockets”, as you said) has made a huge difference in how much I use it and how I spend my time. The sync is also nice (I think it works up to some limit even without a paid subscription, though it turned out I had one grandfathered in); I can basically send webpages I’m reading to it using the browser extension (at least on desktop). On mobile it’s a bit more annoying, but e.g. I’ve printed long newsletters from the Gmail to PDF (paper size A6) and imported the PDF onto it.
It’s perfectly adequate for writing on, but so far I’ve almost never used the fact that it has (a rudimentary set of) colours, though.
