Ok, I am biased, as I am a long-time fan, blew away expectations.
The stage, lighting rig, and sound equipment they brought with was really unbelievable.
The sheer scale, quality of the sound (nevermind the volume) was unreal.
Loved every minute.
I took some pics and video, but be warned, it was with my blackberry, so pics not great, and BIG WARNING, I sang loudly with almost all the songs, can't hear it at the venue, but unfortunately on the video clips, be afraid.

As we arrived:


with the Springbok Nude Girls on stage:

Minutes before U2 came on stage:

random shots of some of the lighting effects and crowd.
