They pay like $40 for the difference, while making it a $200 upgrade, same with the SSD. - Especially since the SSD is apparently really slow with the 256G model.
My next one I'll get 16G simply because those few times (namely, creating Kubernetes labs intended to be ran on Apple Silicon) were annoying to deal with. But for I would wager 90+% of their customer base, 8G is absolutely fine. I've never once had it stutter with heavy Chrome usage, video streaming, or even gaming (not AAA titles, granted) out to an external monitor.
I have now had two (work and personal) - my work m1 air was specced with 8GB, and had major memory pressure and issues with an external monitor. My personal 14” MBP has 16GB - same workload, same monitor, never skipped a beat.
Ended up sending the air back and swapping for one of the old dev ex MBP (intel based).
Once you start swapping, you easily get multi-second delays where a system is totally unresponsive.
A 24 GB M2 Air would be great, but I expect my current M1 to last gracefully for years.
