I do not believe Apple will ever release another expandable/upgradable computer - mobile, laptop, or desktop. We've accepted that Apple will never have expandable storage on an iOS device, but are still mourning the loss of it in Macs. The desire for upgradability is driven by cost - either to get around Apple's cost-gate to get a larger RAM/SSD for lower cost, or to avoid Apple's cost-gate to upgrade later rather than buying a new device. Apple has had great success with the luxury goods model: premium price for the base item, additional premium price tiers for incremental improvements.
