Hey there! Im sure that this is a stupid question and somebody has already asked it, but if someone would humor me that would be greatly appreciated. So from doing a little research I'm lead to believe that the Apple pencil only works with the new iPad Pro correct? I wanted the pencil but I currently have the iPad Air. I wasn't sure why it wouldn't work on an older iPad because isn't it simply a stylist that would work on any iPad? Anyway thanks in advance to whoever explains this all to me!
