I don't think we should hold what "the layperson" does as any sort of yardstick here. My parents also use rather old machines with probably no more than 4 or 8 GB RAM and they're fine for their needs.I’ll be getting 16GB of RAM in my new Mac, but I still don’t know which model yet. My use case isn’t the same as everyone else, so to say 16GB is a minimum for everyone (including consumers who just surf the internet, check email and light work) is a bit ridiculous.
My parents wouldn’t need more than the base RAM. They’re currently running a 21-inch iMac 2019 with Intel Core i3, but it’s doing fine after I did some clean up. The Core i3 is complete trash. When they go to the iMac 24”, they’ll need a 512GB hard drive at least, but no more than 8GB of RAM.
Apple sells machines with 8 GB RAM and 256 GB disk drive because their beancounters have determined it will sell at the price they set. They could probably make it 16 and 512 GB for a marginal price increase but instead choose to price those very expensive as they also know people will want the machine with those and will reluctantly pay it.
I tried the M1 14" Pro and M2 Air base models at a store recently and for basic everyday web browsing and whatnot they would perform pretty identically. But I know that for my uses 16 GB and dual monitors is a definite must and that put the Air out of the race immediately. The 14" Pro is only marginally larger, thicker and heavier than the M2 Air but that fingerprint magnet blue certainly does look great.
I could totally see myself spending the money on either a M2 14" Pro base model or a discounted M1 14" Pro. Base model M2 Air would have to be a helluva lot cheaper than it is in Europe right now.
