I agree with Rainboe and take delight in the fact that all those who deride the A380 (mailnly 747 pilots with a streak of something in their bloodstreams it seems) will soon be flying the second biggest commercial airliner and who ever wants to be second? The problems with the A380 are no more or less than those of all aircraft developed over the last 50 years.
If you fly a Jumbo, get used to the idea that you have a last been overtaken. It's a little like Ferrari in F1. Top dog for a long time and along comes a newcomer/outsider and, oh what a surprise! Not even second any more! At least you Boeing fans have the comfort of knowing that you can't be lower than second!
