Maybe what Apple should do is make the 16GB model the default. Then when you configure the computer you can get a price reduction if you remove 8GB RAM. It would cost Apple nothing and shut down all the complaints that 8Gb is not enough.
I can just hear it now if they made 16GB the smallest amount you can buy "Apple is forcing us to buy more RAM than we need, it is nothing but greed."
Changing the default amount could make everyone happy.
But you know what? Most people who buy the "pro" are not pros. They are only shopping on Amazon and watching YouTube. For a large segment of buyers, the Apple M-series of any model is overkill.
