I would just argue they continue to focus on the wrong thing here.
We need “iPad OS” and/or unleashing of some of the restrictions they’re placing on the iPad/iOS way before we need any more hardware advancements at this point.
The real point of this thread is just that, from the capabilities standpoint, there’s really nothing you can do with a new iPad Pro today that you couldn’t do with the ones before these.
I 100% agree that the iPad hardware is being limited by iOS. It could be so much more and hopefully iOS 13 addresses some of that. But I certainly wouldn’t buy an iPad today based on what might be in iOS 13 as that likely isn’t out for 10 months. I still stand by my point though that this spec bump is not any different than the difference between say a 2016 and 2017 MBP.
