Forgetting the iPad itself (which you're right is more than a notebook), the price difference between the Apple Pencil and a Pencil is £98.60. What does one gain for that?
And you don’t need to pay that much for the Apple Pencil either. I got mine on eBay for 30 quid, minus all the pretty packaging. Granted, I was nervous til it came but it is indisputably an Apple Pencil and I love using it with the iPP at work.
Well, how many pencils will you go thru before my apple pencil breaks down? Have used it every day for a year and a half and still going strong. Adjust your cost and start over.
