I usually resist seemingly useless expensive technology. Like the cameraphone, rollerskate-tennis shoe combos, and HDTV. Until they start saving lives.
You can bet this fellow is glad he had his cameraphone available. But you have to think that it was sort of a "snuff" picture. He engages in mortal combat with a spider, seemingly kills it, then snaps a picture. Why not mount the damned thing on his mantle?
