I have an iPad mini 4 and both Pros for different use cases but was initially excited at the prospect of a 10.5" Pro with the same screen resolution as the 12.9. After spending more time on the 12.9 recently planning some events and editing photographs, I'm now of the mindset that an updated 12.9 will be the ideal choice for me. I really enjoy the screen size of the 12.9 but the PPI of the mini 4 with it's finer on screen elements means the mini is a handy device for travelling but not the first device I would want to use at home. Because of this, I think I would prefer to stick with the 12.9 but there are some real improvements that I would love to see. Apart from the obvious improved SOC, I would love a new 12.9 to have slimmer bezels and hopefully shed some weight. Anything that can reduce the overall size and make it easier to handle would be very welcome. On the hardware side, an improved camera with flash and true tone screen would be great enhancements but after this, it is the software that needs to improve. I still think better use can be made of the bigger screen with a lot of the iOS user interface. I would also love to see the likes of iMovie get some extra features to make it feel like more of a Pro app and geain more parity with the likes of Garageband on the iPad. On the photography side of things where I am really enjoying the 12.9, there are great apps like Snapseed, Polarr and Pixelmator which really let me do a lot of editing without the need for a desktop. With the potential additions of Affinity Photo and Luminar, the iPad Pro is looking quite strong in the photo editing area. This is making me realise how good a product the 12.9 Pro is and how little it would take to make a solid upgrade for me. An upgraded 12.9 is looking more appealing to me than the 10.5 at this time.
