Beautiful design but imagine a slightly thicker wedge shape (or overall) with an easy-to-remove back and maybe 2-4 m.2 slots inside, so one could start with any amount of storage they like and upgrade to however much more they want/need over time... not at Apple exploitive SSD pricing 3-5X ABOVE market but using off-the-shelf m.2 sticks like the vast larger world of PCs can do.
Keep the M-series storage option too for anyone wanting to make a case of "fastest" or some special ability of Apple SSD vs. commodity SSD. Then users who believe could get the overall system installed on 256GB to 8TB Apple SSD (and pay way, wayyyyyyyyyy up for any upgrades that way) AND have up to enormous, additional storage "hidden" inside what might be imagined as a big MBair (wedge design) on a stick. Bonus to this: almost certainly no "unexpected ejections" for SSDs that are directly connected to the board... unlike the joy of that with some- but not all- external SSDs and HDDs we attach externally to any Mac since about Big Sur.
Yes, that wouldn't be a "shareholders rejoice!" bit of engineering but I have to think customers would go nuts for it. Long ago, a Jobsian Apple made an early iMac design with a plastic/acrylic white case, easily removed as one whole piece to not show any panels or visible screws, making accessing (& upgrading) the HDD easy enough for anyone to do it. Here's that oldie (fattened up more than this concept by it also building in an optical disc player and heat management to keep them ancient PowerPC chips cool enough)...
Imagine
THIS iMac "wedge" concept with a bit of that kind of thinking... through a
consumer instead of a shareholders lens.
And while this hypothetical, customers-first Apple engineering creation is being hatched, put a
standardized input or
two on it so that when the Mac guts obsolete it as a Mac, it could easily be repurposed as a monitor for the remainder of the screen life... again, like a Jobsian iMac as late as about 2010-11. Then, consumers would not be buying an overall "throw baby out with the bathwater" device when any one part conks or Apple decides to conk it by vintaging. Yes, that would be ANOTHER disappointment at the all-important "shareholders rejoice!" while jacking up the value proposition of the product for consumers. But maybe a more customer-focused Mac would sell in higher
volume, making a little less profit per unit sold but more total profit on volume... so that shareholders could rejoice too.
But what do I know? I'm just an Apple
consumer. Why care about me when there's shareholders to delight?
