Definitely not true hardware-wise. L2 cache is different from DDR3 RAM is different from DDR4 RAM... in price and performance
Software-wise, yes, the operating system abstracts away the differences and memory is memory
Apple's memory upgrade costs are probably 90% usual Apple bullshit pricing, 10% grounded in reality. I'm thinking that the 10% may be something like the motherboards are designed without memory upgrades in mind, so if you want more RAM, they have to use a special mobo which they prefab less of
Apple uses a unified memory where the memory chips are embedded on the SoC in the first place. The memory modules are on the same silicon wafer the chip is cut from, not separately on the Mobo, and shared directly with the chip in a single pool of memory that the CPU and GPU can access, rather than dedicated memory for each.
Changing the memory means cutting a different piece of silicon for it.
That's like building a fast car that can only go straight. It's impressive but short-sighted and therefore stupid.
Somebody has never been to a top fuel drag race. Impressive does not even begin to describe what those “fast cars that can only go straight” are capable of.
Ha ha. Most people don't use their laptops exclusively for one single thing. I sometimes need a laptop that can go fast but more often it needs to be able to many different things. And some years later, let me swap in some more RAM and an SSD to give it another few good years.
