Hmm not sure yet. I got a bigger capacity phone this year and the transfer speeds are certainly a big consideration for me. But coming from a 14 pro I am really not sure I can justify spending 1500€ on a phone right now. The phone hasn't really made an impression on me I am afraid. Same battery life, same cameras, same form factor, same design, and since the phone will sit in a case the color also doesn't really make a difference. As for the action bottom, dunno, probably a nice gimmick for a few days but honestly the placement is not great (too high on the left, can't reach intuitively while one handing it) and I don't think I will be actively using it in the future, so that doesn't help it's case.
Adding to that the accessories for the 14 pro are really cheap right now (and you can actually get apple leather cases for it lol, imagine that).
As for the USB-C situation. I think right now, for me at least, it is a hindrance since the only devices I own that use a usb-c connector are the iPad and a MBA. All my other stuff like the battery pack, AirPods Pro, AirPods Max, my second personal iPhone all still use lightning. So at the end of the day I will need to carry around 2 cables, especially when I am not carrying my iPad or Mac. So it's really a weird situation right now.
I think I really have to think about it a bit more, but right now I am leaning towards returning it.
