It's not even a "want to tinker" thing for all ... being able to swap in a new/larger SSD is a massive QoL and machine longevity feature to have... even if it goes unused for most people.
Even just for being able to pull a drive out for a backup pr reason, etc
There is really no good reason not to have socketed NVMe in there.
Apple isn't even shipping machines with speeds as fast as are currently possible with existing socketed NVMe tech.
It's all just for forced upgrades at time of purchase.
We are in danger of going way off topic, and I apologize for my part in that, but here's the thing: assuming you're right and that there are genuine reasons normal users need to open up their machines and upgrade and replace stuff, don't you think that Apple know that?
Yes, it could be a very cynical policy of theirs to force those users to sell off and replace when that need arises, but it could also be that it actually doesn't arise much at all.
The point you were responding to was that by far, the majority of users don't tinker, and after 40 years (plus) in this business, I know that to be absolutely true, they don't. Sure,
we do, but it doesn't mean
they do. I find my M1 MBA a bit frustrating at times because it has only 256Gb storage and I have to offload stuff a lot. But a NAS is cheap and reliable, and if I was so minded, the cloud would do anyway. Heck, I could
build a NAS out of a $40 Raspberry Pi come to that. And the 8Gb RAM? Never had any issue to suggest that's not enough. My iMac has 16Gb, and I can't tell the difference in capability or performance unless I'm trying to find it... and most people aren't.
The reality is that what most people want and need a computer to do, can be done on hardware that is 10 years or so old. The OS bloats and so does software, but for the vast majority of people, uses really don't so much.
One other point, if it is a cynical policy by Apple to continuously upsell their products, it's a pretty dumb company considering that firstly, they offer trade-ins in a lot of cases from which they can't really benefit, and secondly, the users can offload via eBay or elsewhere as a used Mac, meaning one less customer for Apple at full price or even via the refurb store.
