New design summary:
- Wireless inductive charging of Apple Pencil from iPad Pro. This would require some way of attaching the Pencil to the iPad, probably with magnets.
- Wireless inductive charging of Apple Pencil from a USB charging stand. Could be a inductive charging case as well.
- For less portable use cases, maybe not used with an iPad but more like a touch(-and-pencil)-enabled iMac (Apple, please!), a vertical conductive charging stand could be viable by just adding some metal contact rings to the Pencil.
