It's like Windows7, it's new, looks newer, higher "tech", has bigger... windows. If you don't have it your competitors will. Other than that, it's just more expensive and keeps the money moving in the industry.I have not been following this airplane too closely, but apart from being composite, why is this thing special? How does its performance look like compared to a similar airplane?
My guess is that its only 5-10% more efficient.....<YAWN>. Someone build that damn blended wing body airliner already! They all look like the same ole B-707 from 1960!
Oh, and it's "green"er.
