$200 too much. The single-camera phone should have been $399. Keep the storage at 128GB if that's part of what's necessary to keep the price down. I'm also fine with the RAM being 4GB if that's feasible for iOS these days. I know it's not for Apple Intelligence, but the point is to make a cheap phone.
At $600, I don't know who this phone is for. You can get the regular Pro or the base model from last year or the year before for the same price and you get way more value.
