Did you actually read the linked story? It's obviously not "rubbish" as it was just done at a major PGA golf tournament...![]()
The article practically came out and said that the only real advantage of the iPhone was to allow him camera access to places he wouldn't usually have access to. A compact camera allows essentially the same benefits, including editing and quick sharing as new models have touch screens and wireless connections.
He can't do action photography, quality of the photos is lower, there is no zoom and there is a reduced level of flexibility with an iPhone. I could sure see an iPhone being adopted specifically for the type of photos that the article talks about, but it would be in addition to other cameras to fulfil other roles.
