I am willing to wager big money that the Apple Pencil will be brought to all other Apple devices as the product refresh cycle continues. It is too big of a design expense to be solely dedicated to just the iPad Pro.
Speaking ex-Cathedra from my little toe!
If it isn’t dependent on the hardware, I think you are right.
Im interested in the Pro, not being an artist Im not sure the Pencil would be useful. But "for people that like that kind of thing, thats just the kind of thing theyd like. But its definitely cute. Loved the video.If apps appear that make people want the pencil, then Apple will make different-sized versions of the pro to cover the range of uses - smaller and maybe larger than the current Pro.
