The thing is, what Apple is doing with memory actually does make sense from a performance and efficiency standpoint. Modern CPUs and GPUs have become so fast that the time signals take to travel between components (like memory and CPU) has become critical (especially in their new M1 products as memory is being shared between the CPU and GPU). That being said, the same definitely isn’t true for storage. Apple soldering SSDs to the motherboard is just them trying to rip their customers off.
