What's often overlooked in articles such as that is that the 787 and the A380 have the same cabin environmental system hardware; developed by Hamilton-Sundstrand for the A380 and modified to work with the 787's mostly-bleedless engines. In fact at 38,000ft the A380's cabin can be held at just under 5000ft-equivalent, and not more than 7,000ft at 41k, which is much better than previous types. The 787 can hold 6,000ft to 43k. Boeing's genius with the 787 was in marketing an airliner directly to the traveller for the first time since the Convair 880 back in the 1950s. Airbus were caught completely off-guard by that and never quite recovered until the later A350.
