Basically only used it to do better professional pictures, there's only so much you can do with a smartphone lens.
That said, for private, nowadays it's more than good enough for most and you're always carrying it around, it's the camera that's there and let's you take the photo as the event is happening that's used.
I would still love to get a smaller dslr for trips, but can't really justify the cost when there's other things that are a priority.
I'm actually really curious as to the next few phone generations will do, since that and battery life is probably going to be the only "true" differentiating factor for most, sooner rather than later.
