Can't argue with the convenience factor. I had my iPhone with me last night, and no other camera. I went to a women's volleyball game last night against UGa. When I arrived I saw that the bleachers across from me were removed, some still stacked on the floor, in anticipation of real seats. I wanted a picture to post on line for the basketball fans who were wondering the status of that update. The focal length of the iPhone was perfect for that.
Then as we were one point away from winning the first set, the men's basketball players sitting in the east end zone stood up to cheer, with most holding up one finger. I knew that was a picture the basketball fans would especially enjoy. The guys were very far away, and I had no zoom lens. I took the picture anyway, and cropped it mercilessly when i got home. It made a 1000-pixel-wide passable picture on the internet. People could recognize the players.
I'm sure practically all of us could relate incidents like that. I think it is great that we always have some sort of camera with us at all times, no matter how much wonderful photo equipment is back at the house. In this case, the iPhone was adequate for the purpose, and maybe for a lot of consumers it is adequate for most purposes. I could have easily had the G7X II in my pocket, but thought of no reason to take it. I knew there would be pros there photographing the game, so I didn't need to. I just wanted to watch the game and hang out with other fans I know. In fact, when I cropped the picture of the players, I left in the photographer up on a ladder above them, and also got the bottom of the scoreboard showing the context.
