I bought an iPad Pro (my first) and the new Apple Pencil (also my first) earlier this year. I think the Apple Pencil is brilliant, and use it for:
1. I write ancient Egyptian hieroglyphic texts, transliteration, and translation in Apple Notes.
2. I do watercolor paintings using Procreate. It's not the same as doing the "real thing," but I can start and stop whenever I have time (no preparation or cleanup) and it's a lot less messy (getting paint on the table, your fingers and clothes, etc.)
3. I use blackletter brushes from Jake Raimis with Procreate to write German calligraphy in the Fraktur script.
