Second display is kinda gimmicky. I have zero use cases but happy to hear some.

Better zoom is good but that's not really hardware. Selfies don't impact most of the population but again not really innovation there.

I don't need stylus and most people don't need it. There's plenty gimmicks but I think real innovation is over. Maybe a last few spurts but nothing much.

Move to the next thing.

Biggest thing for me it to completely remove phones.

Smart glasses / contacts. Whatever floating screen.

I think best system would be hearable smart watch and larger battery system with a powerful soc.

All info syncs between the system. You don't actually have the phone out. It houses the power and brains
