It's usually not the fault of the guy who delivers it to your door. It's usually their automatic machinery that messes up. When I went to the UPS store (FedEx, UPS, etc, all use the same style of machinery) to package my stuff, the lady there told me to tape up all the open "handles" of my boxes because they tend to get "caught" by the machinery. I'm guessing that in this case, the machine actually just punched a hole right into the box without hooking on to something first.
This pretty much can happen to anyone with any shipping company, and sucks for everyone (shippers get brought to court or Dell has to replace the unit which translates to higher prices for consumers).
