I didn't say there is "no difference" between these machines, that's ridiculous. My point is that Apples system-on-a-chip architecture, while giving big performance and efficiency gains, comes with a trade-off. That trade off is availability and pricing of RAM configurations. That 8GB or 16 works for you is great, but it doesn't work for every use case.
