Only thing I'm worried about is a lack of reachability. I really wish UI nav elements would be relocated to the bottom. With the bottom frame of the display being lower, we'll likely be holding the phone lower in our hands so we can tap on things near the bottom, the lower keyboard, etc. But even holding my iPhone 7 cradled in my right hand like I normally do, my slightly above average sized hands (yeah, I measured back when I was getting sized for the Apple Watch because I was surprised to find my wrists were large) can't even reach above the current display, where the controls will be on the new device. I'm also developing RSI from working on the computer and my workshop so much, which makes it hurt sometimes when I really have to reach (I'm only in my early 30s BTW). I hope this doesn't turn out to be an iPhone 6 Plus situation, which I really hated after a year, but the main thing that annoyed me with that was stretching across the width of the device to hit keys and that is mitigated now with the new keyboard in iOS 11. More apps also have swipe to go back gestures now than in 2014, and switching between apps will be really easy now with the bottom shortcut, so we'll see. I hope at some point they add an option to have Control Center/Notification Center as a swipe to the left on the bottom shortcut bar, as a swipe to the right accesses previous apps.
