And so far no-one has been able to articulate what such an advancement would be - especially for iPhone. It's just another form of, "Wah... Apple doesn't innovate anymore. Wah..." Which has been the reflexive go-to chant here for at least 20 years.
As long as Apple is manufacturing and selling 600,000+ iPhones per day, there's nothing to worry about. High level staff changes have been occuring at Apple for close to the last four decades.
To which people will reflexively reply with, "The past doesn't predict the future." Another crowd-pleaser going back a couple decades.
With respect to iPhone, I'm super stoked with my 15 PM. An outstanding device. And am enjoying using the Blackmagic Camera app for making videos to an attached SSD or SD card.
Apple is selling so much iPhones is because it is a “status symbol“.
This is all due to Steve Jobs and Jony Ive who created the Apple cult and made it a status symbol.
This has nothing to do with the current design team who have been releasing the same damn iPhone every year.
