There's a saying I heard somewhere that you should listen to people who talk about their problems, but not when they talk about their desired solutions.
For example, lots of people clamoured for Apple to release a netbook. They thought they wanted a cheaper laptop when they really just wanted a cheaper means of accessing the internet. Apple's answer to that was the iPad. Users still got the basic functionality they desired, while not being bogged down by the heaviness of trying to run a desktop OS on weaker specs.
That is true, back in 2007 where netbooks are still made with 1GB of RAM, slower mechanical hard drive and Intel Atom process.
It was no longer true few years ago. You can build a pretty good netbook with Intel N100, 16GB of RAM and decent SSD. These netbook can be purchased under $400 and provide very good experiences.
So yes, netbooks was horrible back then, but now, you can build a decent netbook running desktop OS.
But we know, Apple never wants to build cheap computers. But I suppose, iPad can be a good devices for basic web browsing and entertainment devices.
Likewise, the people wanting a headless Mac likely wanted to be able to upgrade the ram and storage on their own (thereby saving some money). Apple would go on to release the Mac Studio after Apple Silicon, thereby negating this particular benefit, but I feel it goes to show that users may not always know exactly what they want, much less be entirely honest about their vested interests.
But Mac Studio doesn’t offer up upgradable RAM and they surely made upgrading storage a hassle. My $200 net-top is more upgradable than Mac Studio.
This might be true before 2016, but certainly not true today.
I don't think people really want macOS on the iPad. The surface pro is a thing, and while I am sure there are some people who swear by it, the form factor never really took off and it remains a compromised form factor for most part.
Surface Pro was never meant to replacing traditional laptop, it is a product category for certain group of people. I have seem more Surface Pro on corporate environment, sales rep using Surface Pro. However, I do see more people carrying Surface Pro than few years ago.
I am in the camp that I rather want a comprised experience than carrying two different devices. And with Windows 11, using Surface Pro as tablet is certain doable.
Rather, like you said, they do desire more functionality on their iPad because they are interested in getting more done on it, but are also getting impatient that Apple is either taking their time to implement said features, or clearly has no intention of implementing them at all. This is their frustration showing, and I understand.
I have no solution to this, and I don't think but that macOS would make for a good user experience on an 11" iPad or even an iPad mini.
Remember Apple made 11” MacBook Air, 12” MacBook and 13” MacBook Pro. It isn’t like macOS never ran on 11” screen. Both macOS and Windows adopts different screen size pretty well. And I can say this macOS runs better on 11” screen than current implementation of iPadOS 26 It is a mess to run iPadOS 26 on iPad 9.
