Jeez… if it’s only $150 away from a Pro model, it’s a joke of a product. Just like the iPhone 14 Plus.
These "normalized on 16GB RAM and 512GB " are all highly skewed by Apple's BTO option pricing. The far high volume sold configurations will not be anywhere near that small of a gap. Especially if Apple is still pegging the entry SSD configuration with the kneecapped single SSD package.
If for one product you dip into 2 , or even worse 3, BTO categories to 'even up' the feature set and what really looking at are prices that are designed to "price ladder" you up to buying the system at the next level thinking you got a 'bargain'. "I'm throwing 1,800 at Apple anyway ... what's is another $150. " only means tossing them even more money.
Drop the 8GB , drop a couple of GPU cores and have a much bigger gap.
