The single unique aspect of the B787 Dreamliner which no one has mentioned, but all pilots and Boeing have been waiting for is that this aircraft returns to using compressed OUTSIDE air - not BLEED air, which has been used by all jet aircraft since around 1962.
In this photo you will note 2 nostril type air inlets either side in the wing root - this is where the OUTSIDE air is taken in before being electrically compressed.

Whereas BLEED air travels in the front of the jet engine - is compressed and is then piped unfiltered into the cabin.
Airbus catching up.....slowly.
