Can answer to the second point. I like to pencil sketch and have used the RM2 for this as well. At a hobby level, it's pretty good, almost like pencil on paper.
The only cons I've found vs paper: It lacks some of the finesse/precision of a real pencil (even with the 4096 supported pressure levels), and you can't smudge the graphite with your finger as you might do on paper to make a fill smoother (maybe there is a function that I'm not aware of?).
It the text from your phone maybe on a different layer?
