I'm starting to wonder what sort of peripherals might be possible with the smart connector on the iPad Pro. First one that I can think of is a snap on media hub, like a bar with slots for the various size SD cards. Perhaps Apple will release a first party Smart expansion set up. A thin bar that wouldn't interfere with the keyboard but allow for more local storage. Maybe a battery pack? Apple Pencil recharge + storage? What else do you think could be a possibility?
