Do you expect Apple to make powerful machines first, so that developers will base on that to develop apps accordingly...
Or...
Do you expect developers to develop apps first (e.g. Photoshop) and then Apple will make devices to accommodate those apps?
If the second generation iPad Pros were slow then yes it makes sense for Apple first to develop the hardware and then for Developers to make the software. That's not the case. Even previous generations of iPad Pros do not get utilized enough because there is no such use case. No one wants a tablet that is more powerful than their powerful laptop machine. No regular person complains about not having powerful enough machine to do their work.
Also it's not about the Developers making apps, it's about Apple making iOS good enough to allow Developers to improve it. It's not on third party Developers to improve text editing on iOS, it's on Apple. It's not on third party Developers to provide better access to the file system, it's on Apple. And lastly the issues I have with my regular iPad are not because of third party apps, it's because of Apple. Gestures are not intuitive, half of the time I want to get one thing and get another because the gestures do not make sense on such big screen as 9.7 inch. That's not on other Developers to fix, it's on Apple. Settings menu is a complete mess. That's on Apple to fix. Control center is meaningless if it does not redirect to me to the full Settings menu. That's on Apple to fix and not other Developers. There are a lot of things that Apple can fix to make iOS interesting OS and it has nothing to do with power or hardware. This is what people are talking about. Instead of focusing on getting power that people don't need currently, they should focus on improving iOS itself.
I'm not a power user, so I bought a cheap iPad 6th gen and use it as a media consumption device. But my needs don't equate to everyone else's needs. Somewhere, right now, maybe some one is editing videos on an iPad Pro
Except that people had no issues editing videos in the second generation of the iPad Pros. My point stands. Apple spends a lot of time improving the power of a device that does not lack power. It lacks software capabilities. And it does not start with third party Developers, it starts with Apple itself making iOS desirable enough so that Developers could invest their time in developing good apps for iOS.
Look the thing is that the current iOS is at its peak and it works well for using the iPad as a media consumption device and for digital art. Like I said in another thread removing the headphone jack actually made this new iPad Pro even less pro because no one would want to edit music or video with Bluetooth headphones that have latency.
So Apple wants to push the envelop and do the next thing and they focus on power. What people are saying is that they don't need to focus on power because the current iPads have the needed power (even the previous Pro generations). If they want to push the envelop, they have to improve iOS.
And this is why there are people saying this more and more. This is their way to send a message to Apple that they need to focus on iOS and not on adding better CPU that most people don't need. Now I get that some people get annoyed by this but this is free country. People that have issues with iOS and its capabilities are free to voice them. Ultimately Apple decides if they will listen and consider those people or not.
P.S: I bought a regular iPad because this is my first Apple device and I wanted to first see if I will like iOS before giving more money for iPad Pro. I am happy that I bought the cheaper one because iOS is the thing I dislike the most about my iPad. There are so many issues with it. So yeah I am one of those people that would not buy a Pro (no matter how powerful it is) until Apple makes iOS better.
