These things aren’t contradictory though, and more importantly, will have zero impact on anytime who wishes to just use their iPad as a big phone.
Putting full MacOS on an iPad will absolutely, necessarily impact anyone who wants to use it as "a big phone."
But iPad is no longer "a big phone." There is overlap, but there is overlap with the Macs too. Try using your phone for Sidebar, or Universal Control, or multi-cam control, or using Pencil. You can't do it.
And yes, things are contradictory. Is it touch-first or mouse-first? If it's MacOS then it's mouse-first — but people want it on the iPad so that means it needs reworking to be touch-first. But that will be an inferior version to what we have on MacBooks, so why not just use a MacBook? Oh, there's a keyboard attached? Am I to genuinely believe people want full-blown MacOS on their iPad but wouldn't attach a keyboard? Come back to me on April Fool's Day with that suggestion.
We are firmly at the old Henry Ford quote about "if I asked people what they want, they'd have said faster horses."
Whether people want to accept it or not, the iPad and Macs are different products that do different things. And, more to the point, they generally serve the whole market pretty well. If you need the things that MacOS offers, buy a laptop — there are plenty to choose from. If you need the things the iPad offers, including the portability, then buy an iPad — again, plenty to choose from. And as much as forum and tech reviews love to skew reality by focusing only on fully-specced iPad Pros, let's not forget you can buy a regular iPad for a few hundred £. You can buy a MBA
and an iPad for less than a specced out iPP.
The circular discussion around this is exhausting and boring. "My touch-first device isn't perfect at mouse control" is like complaining that my stereo doesn't play movies —
it's not designed for that!
