On an iPhone, I can take the picture and I'm immediately a button press away from a photo editor and then whoever I want to send it to.

(A camera that automatically tethered to a phone and dumped pictures into the phone's camera roll would mostly solve the workflow issues I'm mentioning here. Would not surprise me if this already exists.)

Maybe. The camera still has to be charged and in mind and hand. (Then as soon as the kids leave the house you're back to where you were and having to carry something around that you might not otherwise.)

> I also know a number of people who don't leave home with their smartphone anyway

I see that... different people have different sorts of relationships with personal electronics. For me, it wound up being that I'd carry a cell phone and that was about it. Even in the pre-smartphone days, when I might have carried a PDA, I either wouldn't or couldn't.
