I think the need for a special presentation for yearly iterative updates to a phone and watch is pretty minimal these days. Just put out a press release
I've never owned an iPhone, and mainly think of the phone I do have as at best a minor addition to my life, but put a battery-efficient modem in my mac and I'll be all over that, because it lets me keep my phone off almost all the time.
Aside from that though, it's always neat to see incremental innovation anyway, but it would all be superfluous to me even if I was in the iPhone game.
It's like coke: "Why advertise Coke? Everyone drinks it."
