While the hinged nose section of the 747 is impressive and certainly makes loading certain (very long) loads easier, there is a height restriction cos the upper deck / cockpit hangs down lower than the main deck ceiling further back, so to make the most of the vertical space available, the rear (side) door must be used for high loads. Only about half of all 747Fs have the swinging nose anyway.

So the point of my first posting here for absolutely ages is that the A380 won't lose out by not having that feature, as the same loads will go just as easily through the side. An internal lift, though, would be a different matter...
