I see RAM and GPU are all built into the M1 chip, so you can’t upgrade after getting your original, expensive, Apple upgrade options. But what about the storage? Will the computer design allow it to be upgraded later by user when third parties start manufacturing the drives?
Sorry there is no internal upgradability in any of the newer MacBook Air/Pro’s! The last fully upgradable MacBook Pro was the 2012 unibody models, the 2012 through 2015 retina models only offered a serviceable SSD drive, RAM was soldered! The 2016 TouchBar and newer have no upgrades. Only the short run of the 2016 & 2017 13” Fn models offered a serviceable SSD but it was very different from the older models and no one offers a replacement. What you buy is what you get! If the think you need more RAM or storage buy it now! Storage can be added externally via the USB-C/Thunderbolt connection. For reference here’s the M1 Mac Mini logic board which is very similar to the MacBook Air & MacBook Pro models
