You are not the target market for the Plus. By posting here, you are likely an enthusiast customer and will value extra features more.I feel like the plus is not needed (unless they are pricing it much lower than current prices). Not enough of a difference in price as it sits now especially with the weaker specs.
A more typical customer will look at the Plus for $899 and the Pro Max at $1099 and quickly pick the Plus. Big screen for less money. You can always bet on that winning in a lot of consumer’s minds. All those other incrementally better features in the Pro Max won’t matter to them.
