Every time a new Apple product of any kind comes out, we have a slew of "unboxing" videos offered up. This is nothing new. They are heavily viewed, so there is a great incentive for creating one.
This couple on the video are very enthusiastic to get their Verizon iPhone 4, especially since they were able to get it a bit early by contacting UPS and picking it up from the depot themselves.
The man may or may not always carry a small penknive in his pocket. It is likely that he just grabbed it on the way out. Small utility knives are very useful for lots of mundane things--opening letters, boxes, cutting strings, etc. That blade was very small, maybe 2" long. The man is not "guttin' critters" or warding off would-be criminals with that thing.
Sure, the woman in the video is no cinematographer. Complaints about framing and focus are valid. But most of the rest of the crap I've read on this thread is elitist snobbery. The man has a Southern accent and carries a penknife--OMG! The iPhone 4 is not longer cool!! How can I ever show my vegan-skinny ass at the next cocktail party I attend if I am using such a low and common product, used by slow-witted white trash rednecks!
Ironically, in the efforts to pile on the poor video posters, many of the "Apple user" stereotypes have been validated by this ridiculous thread. Elitist, snarky, style-over-substance urbane snobs who wouldn't last ten minutes in the woods alone.
The woman on the video doesn't know how to properly work a camera. They are both a bit too enthusiastic about getting a Verison iPhone 4--it's not even really a "new" product! That stuff is all fair game. But the rest of the discussion here is just sad.
