Let me break it down to you.
During the Intel area… people went the iPad route as a laptop replacement as you mention “pleasing to use,” right? What has changed since then… it’s not as the iPad platform hasn’t improved (maybe not to your standards), but that the Mac has improved immensely with Apple Silicon.
Apple Silicon (M1) was introduced for the Mac in November 2020 and that brought a lot of praise… so, what did Apple do in 2021 for the iPad, they put the M1 chip. This caused so much hype and it speculated that Final Cut Pro or Logic could make an appearance on the iPad.
Although, Apple didn’t make any promises… we assumed as much. I was part of the hype train as well, thinking that something big will come in WWDC 2021. People even bought M1 iPads with the intention that if nothing came of it…. They would return it. And so, WWDC 2021 came and they were a lot of disappointment (including me).
And with displeasure in Apple, most people decided to return the iPad. But if you look closely, the people who went the iPad route as a laptop replacement… didn’t use it with hopes of Final Cut Pro or Logic. So, I think you are lumping in people during this period.
I think we'll just have to agree to disagree. From what I've seen, following the iPad as a laptop replacement discussions for many years, is a fair amount of people started trying to make the iPad into a laptop replacement due to a golden combination of the iPads getting very powerful, getting mouse, keyboard, and gamepad support, and other niceties in iPadOS - which compared more and more favourably to the Intel MacBooks of the time.
Forget software for a sec: I preferred the hardware of the iPad Air 4 and then the iPad Pro M1 to my 2018 13" MacBook Pro. The MacBook Pro was heavier, the keyboard was worse, the screen was worse, the battery life was worse, it was far slower, and it was hot and noisy. I used the iPads 90% of the time.
But now that I've got the 14" MacBook Pro, suddenly the equation is different. The screen is better, the battery life is better, the performance is better, it doesn't get hot and I never hear the fans.
A multitude of people went to the iPad over their laptops because of the hardware. They put up with and tried to work around the shortcomings of iPadOS, but now that Apple silicon MacBooks are around, the whole landscape is different, and many have gone back to the MacBooks. They don't feel the need to try to make iPadOS work in a laptop replacement scenario anymore, because the hardware advantages of the iPad don't stack up against the MacBooks like they used to.
There's no sense pretending iPadOS doesn't have shortcomings as a laptop replacement. On the flipside, there are aspects of iPadOS that I really liked compared to macOS when I was using it. I have seen many people try to make this discussion a battle, where either the Mac or the iPad must win. Pointing out advantages of the Mac doesn't mean the iPad is worse, nor does pointing out advantages of the iPad mean the Mac is worse. But it seems if you do point out a shortcoming of the iPad, many people take it as a hit to the iPad side and feel a need to defend it.
It is possible to accept that iPadOS has shortcomings in the context of laptop replacement, without saying that iPadOS is a bad OS, or that the design philosophy behind it is wrong, or that it isn't perfect for some people already as a laptop replacement.
