I do both of those and I dislike the RM2. There's little space for notes above and below the PDF page, no infinite canvas. I have more space on the back of a printed PDF (to the left of the current text page) than in the RM2. So, all note taking in a PDF for me is just keywords, while I would much prefer to put text and drawing,s graphs, etc. all around the PDF page.

So, for the last few months I have barely used the RM2 and have gone back to pen and paper.
