I will open this up to the 12.9 and 9.7 models both for all owners. What are your Top 2 yes only 2 be selective must have exclusive to the Pro line only features or updates you must have. Remember theses are iPad Pro only level they will not be available on iPad Air 2 or older models. #1. USB Drive support. Professionals likely have alot of data to carry around. #2. Bluetooth Mouse support. It would help me in Microsoft Office and many other apps maybe even games too. We already have Bluetooth keyboard support. The iPad Pro would be great to play some RTS games.
