What? People lie all the time on forums. I am not saying you specifically are, but a lot of people do.
But we'll see what happens if Apple ever actualy does put MacOS on an iPad. People said the same things about large screen iPhones ("I don't need a giant phone on my pocket") and even the original iPad itself ("it's just a big iPhone").
Look at the screen resolutions (in pixels) of an iPad. Then look on the screen resolutions of the current entry level M1 iMac. You see the difference? You might not be able to imagine what this means for touch targets or the number of lines you can see in a document… well, here we go:
24” iMac uses 4480-by-2520 resolution at 218 pixels per inch
11” iPP 2388-by-1668-pixel resolution at 264 pixels per inch
I think that most people will agree that the 24” iMac is an entry level, consumer device.
I also think that the 11” iPP is the right size for an iPad assuming touse it as a tablet wherever (your mileage may vary, I have siblings who ”evangelise” for the 12” ?)
Can we be generous for a minute and say that a a touch target when you just would remotely connect to said iMac is roughly half as big on the iPad screen (when scaling iMac onto iPP; otherwise you have a lot f scrolling to do which I suppose makes the whole procedure after a short interval quite tedious and not really ergonomic, right? ?)?
Even worse: imagine that you do so without external hardware (keyboard, trackpad/mouse)… because that’s the iPad “default”. ?
As many - to the astonishment of many others - pointed out, there is a not actually small group of people who are happy with the iPadOS interface as it is. They are not happy about various bugs, inconsistencies, and they might miss features (yes, e.g. extend “desktop” when connecting a monitor should be a general option ?) - but iPadOS does a lot of things right for what it is.
