Having said all that, Apple could easily have made it 16GB cleaned up the market place and nobody would be talking about Neo being under spec’d. But Tim Cook has to be a Tim Cook and squeeze every last penny of profit. ;-)
I think this has more to do with binned A18 Pro SoCs which enables Apple to do this with economies of scale. A later version may get the 12GB variant of the A19 Pro SoCs.
This guy [1] that posted about his series of plastic laptops over the years is a telling indictment of what the PC/chromebook value range is about. Hinges easily damage, bits and pieces falling off, can't go from closed to open with one finger, etc. In my region in Australia schools require parents to buy a laptop and the choice is between PC and Mac (Chromebook not allowed); before the Neo getting a Mac would be a budget constraint, especially for their children, but now it is such an easy sensible choice.
