How have you found using the SE?
I've really liked using an old 7+ for the last 9 days or so, although I can tell if I was out and about in day to day life instead of working at home the battery would have been awful... I think it will make me enjoy/appreciate the 12 Pro more instead of going straight from the 11 to the 12 as there wouldn't be that much of a difference.
What it has made me realise I miss though is Touch ID..Really hope they integrate it somehow into the 13 whether it be under the screen or on the side like the new iPads
