Although I complain about too much technology to the point of creating an entire collection, called Phantoms, to show how it's the demise of society as I've known it, here's an instance where it definitely came in handy.
When I go to the beach lugging beach chairs, umbrella, towels, books, etc, I leave my camera behind to lighten the load and avoid damaging my equipment. However, now that the i-Phone takes such good pictures, I can whip it out if I see something I can't resist.
Sure, I can't control the f-stop, shutter speed or the focus and the file size is limited, but when there's a choice between capturing the image or not, I succumb.
In this case, if I would have waited to return the next day with my Canon, this creature would certainly have been washed away.
