Everyone mentions the remarkable but the degrading pencil tips have got to be the stupidest, most infuriating, most egregiously rent-seeking product conceivable by the human mind. I refuse to play that game. Why would I want that feeling anyways? On paper I choose the slickest paper and exclusively use a fountain pen as wet as practical without being messy. I understand the glass tablet surface isn't nice for writing and I appreciate the alternative, but the $1.50 a pop guarantee that the tablet becomes a paperweight when remarkable goes out of business is insane. (On that note, I also seem to recall that features have been removed from the device via updates.)
There are a bajillion 3rd-party sellers for EMR nibs; they're just little bits of plastic.
You might be interested in the Supernote, though - it's a similar device to the Remarkable, but it comes with a hard-nib pen and has a slightly soft surface on the screen, which gives it more of a pen-on-paper feel.
