One thing to think about regarding memory and the fixed internal storage. 8GB while sufficient for most light duty users still causes some swap activity to write back to the main storage. While SSD/Flash based storage life-cycle has proven to be extremely durable, continuous swap activity does consume some of the finite write cycles for the chips. With older/slower physical drives this was usually an after-thought.

Additionally, storage failure in any way now requires logic board replacement versus a separate drive swap. Lastly, if failure does occur, what mitigating factors does Apple (or any authorized service agency) take to ensure personal/private data is completely destroyed? Non-fixed drives don’t have this problem - replace the defective drive and load back up, assuming the consumer retains the original drive.
