So it appears Apple has decided that Bluetooth keyboards take a back seat to Smart Connector enabled keyboards. But what else can the smart connector do? Can you charge the Pro from it? i.e stick it into a dock, charge it, and have secondary speakers? Obviously there is data transfer. What is the throughput? Can I create a music keyboard or some DJ equipment and set the Pro in it and interface with it? Can I feed it a video signal? How about creating a Mac OSX powered screen-less Keyboard computer that you plug in a Pro for the display. The best of both worlds: A full function OS X running Mac, or snap; a iPad Pro running iOS 9 I can't wait.
