An Apple Store salesperson today recommended the new M3 MacBook Airs to my mother, because "The M3 MacBook Air will last longer than the M2".
So how true is that? This salesperson has brilliantly/unwittingly struck at my mother's pet peeve, since her previous 2011 MacBook with outdated Safari and Chrome can no longer display online banking webpages properly.
I'd think that the M2 and M3 being the same family would still have roughly the same long-term lifespans, for the sort of light home-office work of the sort my mom needs at least 5+ years. Is the M3 really more future-proof as the Apple Store salesperson claims?
The other issue I have is the small nonupgradable 8 GB memories in both base models. Curiously, the base models are $100 different, but the M2 + 16 GB upgrade costs even more than the base M3. Maybe the pricing will change again in a few months, but my mom needs a replacement computer this month!
Most people do prefer all in one's of course. I stopped using the 2010 or so MBA. Still works. The iPad Pro is my laptop, with keyboard, trackpad and third party mouse. I use it for musical scores and showing off photos from the Nikons pretty exclusively. Size and portability matter. For these two uses, a laptop configuration is less suitable for me.
Desktops and laptops are still hundreds of times more efficient and useful to me than any mobile OS.
Even with the gamut of goodies.
If your mom upgrades so infrequently, it's like cars. The newer model will obsolete later.
My phone and some other systems fell off support, and can't get software upgrades. (Other than Linux, of course)
I suspect that's the rationale, even if the M series all seem interchangeable. Or maybe it will run out of horsepower later, as software gets even more demanding.
I doubt that she'll need to count cores and GPU's.
