How often have you had a memory chip fail? I ask because I only have had it happen once in my lifetime that I can recall and it was for a very dumb reason.

I wonder why so few people ask Apple products of such questions -- "what if my SSD goes bad, does it mean my computer is now completely useless?"

it's basically the same as asking what happens when your M4 Apple has a fault. It's soldered based on the desire to use the ram as part of the GPU.

Without that, it's really not a interesting solution.

demanding replaceable ram means also not wanting the benefits of the integrated memory
