There are several things I do with the Apple Pencil. Things like taking notes, drawing out cover or building layout ideas, and editing my photos. But the most important use and the reason I made the $129 investment is for editing documents. A few years ago, I made the jump to a paperless workflow. I use to print out my drafts and do all the proofreading to paper copies before scanning them in for the archive. When I went paperless, this process was the largest one to change. I use Scrivener as my go-to writing platform, but for editing, I export the draft into Pages and use the annotate feature to markup the document for corrections. Then I take those redlines and go back to Scrivener and make the changes to the text. I know that some of you are going to point out that I make the edits twice. You are correct. I do this, so I have a record of my complete process from start to finish.
