Just picked up a gen 2 Apple Pencil for my iPad Pro 11" and I'm kind of confused what its purpose is. I mean, it writes and draws, and can tap apps and launch them and change pages, but so does my finger. Am I missing something here? Does it do things that I don't know about (which is entirely possible)? I spent $125 on this thing and so far, I'm not impressed. I bought it at Costco, so I have 90 days to come up with some reason to keep it. Someone tell me it does more than scribble notes and draw pictures.
