And in this case old is not a bad thing, while the orginal 747 design is 60's, many parts and systems have been upgraded over the years the 400's have a new wing design, better engines and electronics.
747 hull 02 still fly's almost everyday as a testbed for many projects (you can watch it at Boeing field in seattle, it's white with red stripes) (01 was destroyed during static testing)
While I like boeing (they bring alot of money to this area)
I also see the value of the Airbus design, my biggest problem with Airbus is the economics of the company (huge tax subsidies) allowing them to sell planes based on cost rather than superior design
