A revival of the 12” MacBook would be amazing, but give it to me as a premium device - not an educational market positioning.

I want a real M-series chip with RAM upgrades, an OLED display, etc.

Like the little buff 12” PowerBook https://www.macworld.com/article/225194/ode-to-the-12-inch-p...

Somewhere on my list of projects is "Gut a 12" Powerbook and put the guts of a modern M series Macbook in it". The chassis is so spacious and the Macbook Air logic boards are so small, physics is not going to be a problem. Just hooking up screens, the keyboard and trackpad (using the original, natch), and ports. There's already a high-res display swap you can do in that chassis to get to 1400x1050.

Hmm now I want to see this done in a PowerBook 100 chassis with a Sharp Memory LCD screen.

I still remember when the Air lineup was all about being small and light.

The MacBook Neo and the MacBook Air (at about the same weight) are 10% lighter than the original Air.

Exactly. This with an M5, OLED, today's keyboard/trackpad combo, 16GB/24GB RAM, 2-4TB of SSD and it would be an instant buy

They make something like that, but it costs a bit more.
