Wow so much ego over "what I want is normal, what you want is weird".
Apple started with one type of phone. Now they have 4.
Likewise their desktops, started with one range, now have about 8 types of laptops and desktops.
Overtime they could easily expand the phone range.
They have address first prefer priorities, but things like better cameras, durabity and waterproofing will become standard with time (maybe after competitors get too far ahead of Apple).
