I'm really hung up on why Apple won't do what Intel has done with their freaky Intel Radeon NUC or new Xeon chips which is to on package some high bandwidth ram and allow expansion to ddr5 as a slower ram tier. we are stuck on apple with apps that want 8gb plus like chrome and then they want to gpu accelerate which eats more of the ram and I don't get how you can buy anything configured like this with less than 32gb of memory and expect long life out of it.
