Then why not increase the base model to 512? Doubt Apple has too many issues with supply or pricing given the volume & status. If I opted for a base M2 Air I'd be seeing a downgrade in performance versus my M1 MBP. If coming from an older Intel Mac likely ok for basic use, however the reduced flexibility of the base models is pretty well illustrated as the YT channel is showing reasonable real world tasks not just repeated benchmarks.Could have been a decision based on supply rather than cost. That’s not necessarily a justification, but is a possibility
Had Apple gone with the duel channel 512 drive they would have gained a lot of favour. I suspect they don't want the M2 Air & MBP to be too close to the more expensive 14" & 16" MBP as many bought the original M1's as stopgap yet found them more than powerful enough so never upgraded.
