Only caveats - I like aftermarket cases more than Remarkable's. I bought one one from Amazon for about 30$.
Also I've been using staedtler's digital pencils, works great!
I've long thought about getting one of these, but don't want to shell out $500 if I can't comfortably write on it.
Writing resolution is pretty good and most importantly it tracks the tip precisely. It's not as sharp as a real 0.2mm mechanical pencil, but you can write legibly down to ~2mm line height (1).
The larger factor is the contrast: the reMarkable screen is light grey so I usually write larger than I would on white paper.
(1) not at the very edge of the page, but maybe v2 fixes that
That being said, there is still room for improvement, particularly with reading (vs writing, which this device is very good at).
I mostly use it this to replace stacks of notebooks (my brain thinks better with pen and paper in hand, but with all the digital conveniences in hand. This device is the best that I've tried for writing (and I've tried many, including an ipad pro)
Cons: historically, the price. No blacklight. Clearly the device has been optimized for writing, not reading, although supposedly 3rd party ebook readers like Apollo are good (the device is not locked down and has a hacker community).
No browser, no clutter, just... really, really useful paper that's always there and doesn't get misplaced later.
