What you described is a very different product. I'm also in the boat that would love the 12" MacBook to return, and the main reason for that is the form factor. The 12" MacBook is EXTREMELY thin and light. An iPad with a magic keyboard is thicker and heavier than a MacBook Air, and the iPad doesn't not balance the same way a MacBook does with it's built in hinge etc. Obviously I'm not even bringing up the OS difference, though macOS is far superior to iPadOS, and I don't see that changing anytime soon even with multiple updates. I own an iPad and it's a great accessory, but my Mac is my main device. So yeah an iPad will never replace that 12" MacBook experience.
You are running through open doors...
I was just being a bit sarcastic in my last comment, because I feel that this is what Apple marketing seems to think: that users who want a super portable device should go iPad. Even though it is actually heavier and thicker when a keyboard is added, and let's not even discuss the toyOS it is running... But all that does not seem to compute inside Apple's head. To them the iPad is a great computer.
I am in the market for a
high-end ultra-portable Mac laptop. I'd be happy to spend thousands of dollars on a 12" MacBook with 64GB or even 256GB RAM and an 8TB SSD. Alas, I am probably the only person in the world who wants such a device, it seems. I don't need an M5 Max CPU, nor three Thunderbolt 5 ports, but I want small and lots of RAM and super lots of storage - all in one tiny portable device, with no external HDs, no dongles, no cloud storage.
Sadly, as has been seen with the 12" MacBook, this is a market that no one truly understands at Apple, nor knows how to market properly.
Ultra-portability requires
extreme miniaturization, which incurs much higher costs.
The tiniest ultra-portable laptops, Walkmen or Discmen from Sony were
never their cheapest models. To the contrary. Those were always premium devices. You paid for the smallest size.
The terraced, layered battery in the 12" MacBook for example was much more expensive than the cubic block batteries in all the other Mac laptops. Developing the non-moving force-feedback trackpad was much more expensive, compared to a standard yet bulky mechanical moving trackpad. The R&D that went into using the WiFi antennas as speaker ducts to get amazingly clear and loud sound out of very small speakers incurred quite some costs, compared to the tinny sound one would get from regular tiny speakers in such a small device. Just to name three examples.
That is why the 12" MacBook was actually quite expensive in comparison to a MacBook Air.
But in most people's heads, people who tend to think "bigger is better", these tiny MacBooks should have been the cheapest Macs - because smaller to them is worse (hence must be cheaper).
It's a tough sale. Apple's marketing department would at first need to educate the consumers that miniaturization drives up prices, that a tiny high-end MacBook would cost
more than the highest high-end MacBook Pro.
So the 12" MacBook was this weird device, that was actually a somewhat higher-end ultra-portable, but never properly marketed as such by Apple. And consumers just compared screen sizes and expected it to be cheaper than the larger MacBook Air ... not understanding that miniaturization below a certain size becomes
more expensive again, not cheaper.
And Apple marketing was too dumb to point this out or too lazy to educate consumers about this. They never really knew what to do with the 12" MacBook. It was probably the brain child of Jony Ive - but the marketing department never got the memos...
