Hahah I meant the two device thing was a possibility after the Mini is discontinued (if it is). I will almost for sure go with either the Mini or new SE after the SE1, as two devices is definitely extreme. I wouldn’t consider it unless the smallest iPhone in the future is closer to 6”. I really really hate using a phablet when I’m out and about (I tried for a few months and just got more and more frustrated). But even 6” is probably less headache than two devices, especially with no software integration between them. I dunno, it's just a no win situation, seems like.
As far as Face ID vs Touch ID, I’m sure Face ID is very convenient, but I’m very uncomfortable with/wary of my device having that level of detailed knowledge of my face and being able to read my expressions and my eyes at all times. It’s too personal for me, so I always put a sliding camera cover on my devices, which wouldn’t allow Face ID to work anyway. So that’s a big reason why I might choose SE over Mini. Just a personal thing.
Edit-
Actually, can’t an Apple Watch unlock an iPhone now? I have a watch so maybe I could get a Mini and just use that instead of Face ID.
Edit again-
Never mind, I believe the watch only unlocks if I use Face ID and I’m wearing a mask or sunglasses. Also it would only work for unlocking the phone, not Apple Pay or Keychain etc.
