I loved my RM1, by far the best e-ink reader/note taker I have had.
I had to switch to a Boox though, as I grew bored of having to maintain a Windows VM with a downgraded Calibre to convert my Amazon purchases to ebooks for reading on the Remarkable. I now have my Boox with the Amazon Kindle app and can natively read my books, and the writing feeling is almost as good as on the Remarkable.
