1 Yes. I don't want to carry two devices. Just one.
2 No, just a good camera. Lot of camera stuff these days is extremely excessive for taking a sunset picture, or a selfie.
It seems that given performance has basically peaked out (yeah, you need 8gb for an android phone, lol), phone manufacturers are increasingly using pointless gimmicks. AR games (lets just give you 1,000 dollar smartphone to your kids), gaming phones (really, like there are many decent high end games on smartphone platforms? nope), special camera doddlebots. I've never been sold on stuff like that.
If you are a genuine photographer, you get an actual camera with a proper optical zoom. I guess kids or pets in action shots is about the only reason I could come up with for a second camera with optical zoom. But myself, nope, not fussed.
The 950 I am using ATM, takes great pictures. I don't really need anything better than that, maybe faster focus/picture processing, but that's about all I'd change.
