My iPhone 14 Pro Max 256GB ships 21 Oct - 28 Oct (but previously 26 Oct - 2 Nov)
I find the resale value of the higher capacity is very marginal so never really tempted to go for 512 / 1TB until a time I ever get close to filling up 256 which I'm nowhere near doing at the moment, I guess if I start taking a lot of video maybe but all I would have to do then is spring clean now and again by archiving them off my phone to my 36TB NAS
