Okay,this might end as a typical A<>B war... not my intention though...
As people always speak about very modern, revolutionary technology on 7E7 and 380.
What exactly makes the revolution. Is it "just" the size of the 380? I read about new engine technology for the 7E7, but technically, what is the revolution?

Regarding the 7E7, it will feature a new generation of engine technology (no bleed air), as well as a wing and fuselage made primarily of composite material. It will have interchangable engines, a first. The 7E7-300/800/900 allow an airline to take commonality to a whole new level. The Base model is predicted to have a range of 8500nm, or roughly 98% of what an A345 is capable of. All for a sweet aquistion cost of 100 mil, undercutting the A330 by approx. 30 million USD.
The "Revolution" is that airlines now have a single basic airframe that can fly short haul, medium haul, long haul, and ultra-long haul routes economically. Its small size means it can break even with lower numbers of passengers than an A330 or 777, possibly opening up many new Trans-pac non-stops.It also means low risk, something on the mind of many many airlines right now.
The 7E7's Entry-Of-Service is set for 2008, a time when many early 757 and 767, as well as older A300, A310, will be reaching the end of their useful life. The 7E7-900 will probably compete directly with the A330, while the 7E7-800 will be sized close to a 763.
The A380 features extensive use of GLARE a fiberglass/aluminum alloy as well as laser welding. I'm not really an A380 follower, so this is about all I can say.

these days the main goal of the big aircraft manufacturers, such as Boeing and Airbus seems to be efficiency. Now making an aircraft efficient depends on many factors. The main factors would be cost/maintance, capacity (pax and cargo), range and fuel efficiency....much like a car I suppose. Another important factor is the market. The manufacturers must be confident that there will be airlines out there that will buy the finished product. In my opinion that is the revolution. Hope this helps!
