This is a great topic
@Sami13496 and a great discussion filled with insights for this “buy the best and future-proof your purchase” adherent. I’ve heard enough to cause me to reconsider my perspective, but there is one dimension that I haven't seen addressed in the comments which are largely centered on “first cost” and resale/salvage value. That missing dimension is “operating cost“ — the cost of maintaining and enhancing the system over its life — which historically often exceeds first cost with business system investments. Of course in this case we are largely talking about consumer investment/expenditure as has been pointed out.
However, I think there is still an operating cost dimension: i.e., the “cost” associated with enhancing and maintaining the system. In the case of Apple silicon, “enhancing” largely translates to purchasing external storage or performance-enhancing applications .. and maintenance translates to effort to troubleshoot and correct performance-related issues. While we may not be paying someone to troubleshoot and correct performance-related maintenance issues, our time represents opportunity costs — which has value proportionate to what else we could have been doing instead of chasing performance-related gremlins.
In my experience with purchasing “maxed-out” iPad and Mac configurations, I’ve spent almost $0 on external storage/enhancements and experienced near zero performance-related issues. In fact, I rarely experience the issues I see reported on MR and elsewhere. I can’t prove objectively that this is due to having high-end CPU, GPU, RAM, and Storage configurations, but I am of the belief that the device configuration is a big factor in my relatively problem-free Mac experience over at least 2 decades. Please note that I’m not arguing against the proposition of thus thread — just curious to see if others have had this seemingly contrarian experience.
