So I agree with
@exoticspice1 that 8GB can be a fine configuration just as you argued that 256GB of storage can be a fine storage size depending on what you want for it. But for a $1600 machine regardless of the name “pro” and it has both 8/256? That’s … limiting to put it mildly. Of course it tries to justify its price through the screen/speakers/etc… but I fully agree that at that price it should have one or the other (preferably both) specs higher.
Part of the issue here of course is that the base M3 14” is the same as the base Air/mini and shares the same upgrade path. In some ways storage would be easier to offer a higher minimum storage tier as simply there are more of them after 256GB. But the base M3 only supports up to 24GB of RAM, which means only one less used upgrade after 16 GB which again is part of the problem.
To be honest from a purely compute perspective the base M3 in the 14” pro (again I don’t care about the name but the price) is a good idea and a perfect fit for some, but the memory/storage tiers for the base M3 are outdated and look particularly bad in that device. Again, 8/256 might be justifiable in a $600 Mac mini or maybe even $1100 Air (maybe … even then … hmmm), but not the $1600 pro.
Personally I think the storage is easier to offer a bigger base but I agree at least one of them should’ve been higher. A base starting at 12GB of RAM for all M3 models might’ve worked (12, 18, 24? or 12, 18, 36?).
