Well, it's certainly interesting news, and I never ruled out seeing an Airbus in Easyjet colours.
Deviating from the tried and proven Ryanair/Southwest model doesn't necessarily imply imminent failure (although it doesn't seem to rake as much profit).
I agree that JB was an inspiration (well, the press release/Stelios mentioned them, along with FR and WN).
According to my no-frills study aid, the JB decision to acquire Airbus 320s was based on these facts:
-24 more pax than the 737
-more legroom for pax than competing Y class cabins
-burns less fuel than the 737
-slightly wider seat bottom (!!)
Another interesting day in the aviation world.....well, it would have been a bit boring if it was just another batch of 737-700s!
