I disagree, it's like saying "what a ****** MacPro, it does the same thing as the MacBook Air".I think this is kind of harsh. I agree with the part about no unique features for the Pro models, but that doesn't mean it has no future or it is a scam, it is just a higher end model with a bigger screen than a mini. If they called it an iPad Premium it might be more accurate.
Clearly certain things are missing, but an iPad Pro can do a lot more than an iPad mini and faster. The iPad's problem is not iPadOS itself, it doesn't need macOS, it needs certain apps that currently can be perfectly ported from Mac to iPad, without any problem, adapting those apps to the iPad's touch interface.
MacOS will always be a freer system, because it was born that way. iPadOS will always be more limited because it is a totally closed system. That does not mean that the more advanced iPad users will not demand more advanced programs to squeeze even more out of our devices.
In my case, I repeat, I would love macOS Office on iPadOS and leave behind the current limited iOS app, which for a college student may be enough, but for people who work is quite limited.
Other people want Final Cut, full Photoshop (although this is there, but I think it's not what was asked for in the end, although in my case I use Pixelmator Photo).
People don't want iOS apps on macOS (some do, but not all), but if that is allowed, I think it is perfectly possible to port macOS apps to iPadOS (not iOS). An iPad Air or Pro, with the A14, and keyboard and mouse support can perfectly well with many Mac programs, Apple just needs to allow it.
