I don’t think this will ever come from Apple. There really is no possibility let’s just be honest. Not sure why people keep asking to have macOS on an iPad.
Also using an iPad with a capable trackpad and keyboard as a daily driver can show you that it will eventually become it’s own very powerful OS in the future.
With Extended display support, Stage Manager, some apps that I (personally) use regularly like Davinci Resolve, Logic Pro, Photoshop, Lightroom, GSuite. iPadOS has a great future ahead of it. And don’t forget all other apps that already exist like banking apps or other iPad apps in general that work better opposed to a web browser because a desktop app was never created. For example: Gmail for iPad…
It’s definitely not a Mac and obviously more can be done on a Mac but it’s very capable on its own. Hopefully they release the better magic keyboard with a bigger trackpad.
