The Apple Pencil is a worthy upgrade for anyone who wants to do some drawing or other artwork on an iPad. There are cheaper alternatives, but they're not nearly as good. And even if you're not an artist, there's a certain pleasure in using the iPad like a pencil and paper. (Especially if you're signing digital paperwork frequently.) Keyboards are more situational, and really only useful in the same situation as a full laptop. If you think you need one, you absolutely don't need Apple's expensive accessories — save some money on a wireless board from Keychron or Anker instead.
