I have a 15 and have had iPhones exclusively since the 11 (first one was the iPhone 2) but really wish there would be an occasional crazy one.
Don’t get me wrong there are good enhancements but maybe a completely see through version one year then the next make it rainbow pattern or have inbuilt LED. I remember LG bringing out a modular phone that you could switch out components like camera or extra battery or torch etc.
What would be interesting to me is if they could somehow hand off devices in close proximity. E.g I have an iPhone 15 so no Apple intelligence but I have a Mac and an IPad Pro M2 so if it could utilise those devices for the query and sync up I wouldn’t mind a wee delay.
