Apparently some of you have not read Boeing's press releases very carefully. I now it is all Boeing marketing spin, but they do give some insight as to other advantages, both to Boeing, and the airlines of this new aircraft. Without going back and digging up and referencing the press releases I remember a few things off the top of my head.
For one, Boeing is working on it's manufacturing techniques and processes to greatly reduce the cost of producing the airplane.
I believe they have plans to make these cockpits common with the 777 cockpit, which means they are working on an airplane family similar to what Airbus has done. Hey, I know all of you will say that Boeing is behind Airbus here, but on Airbuses earlier models they copied a lot of things that Boeing pioneered. It is always a good idea to borrow your competition's best practices.
I think they also said something about increasing the amount of composites used, or developing a new composite, that will reduce the number of heavy checks that have to be done on the aircraft. These types of things decrease maintenance costs for the airlines, as well as increasing the lifespan of the airplane.
There are many others mentioned, but it is definitely a step in the right direction for Boeing.
Don't quote me on any of the technical stuff, I am sure I misstated something, but you get the idea, its more than just looks.
