The statement in bold tells me everything I need to know about how out of touch you are with the average low-end Mac purchasing demographic.
How many people do you consult for when it comes to tech purchasing decisions? Do you do this sort of thing for a living or is this something you dabble in whenever a friend or relative asks?
I ask because I actually DO this stuff for a living. And when I'm off the clock, I still do it! I live and breathe this stuff and for everyone I consult, I do so, not from the standpoint of a techie. But from the standpoint of someone who wants a computer to last as long as humanly possible. Not someone who can afford to buy any computer Apple makes. There are fewer people like you in that regard.
Incidentally, I'm guiding people not toward whatever fits snugly today. But what will be continuing to run smoothly several macOS releases down the road, because, UNLIKE you, most of the people I'm guiding CAN'T afford to buy any computer that Apple makes and they need to spend WISELY to make sure that what they buy lasts them as long as possible.
Shortchanging yourself on RAM doesn't sound like the how-to-get-rich strategy that will ultimately make a difference. Then again, you can afford to buy low-end Macs every 3-5 years rather than spending the $200-400 extra to stretch that out to 7-10 years, clearly overlooking the fact that this is poor value, even RAM is not something that ultimately matters to you.
But not longevity and future-proofing because you're rich and can afford to buy something new whenever you want. Got it.
I have 28 Apple certifications. I have 5 Jamf certifications. I've got 11 Microsoft certifications. I work with tech-illiterate consumers EVERY FREAKIN' DAY OF MY LIFE and have for several years. When I'm not a tech practictioner, I'm a tech consultant. It is literally my bread and butter to make sure my users are on not only what will serve them today, but what will serve them well into the next decade. Yeah, I definitely know better than millions of consumers who don't care about specs differences nor understand the potential long term ramifications therein. But, please, go ahead and enjoy your M2 MacBook Air and tell me all about how long 8GB of RAM will be good for, since I'm guessing your vast wealth also afforded you a crystal ball.
My requirements and the requirements of the thousands of folks I support are two different things. Incidentally, you might want to heed your own advice.
