One thing about the A380 confuses me...

Do a simple sum based on pounds of thrust and maximum take-off weight, and compare the A380 to other aircraft.

The 757 comes out at a healthy 0.34, the 747 comes out at around 0.28, while the lethargic A340-300 comes out at 0.22.

The A380 is just better than the A340-300 at 0.25.

So will the A380 be a lardy beast? Or will the massive wing area overcome the relative lack of power?

...and here are some figures for the insomniacs out there...(information from manufacturer sites)...
