Rather than brave the crowds in the main hall I spent most of my time upstairs in the Nokia-sponsored overflow room. It was really comfortable, and a great way to watch the presenters. The WiFi was flawless, the power outlets plentiful and well distributed, and the coffee and pastries were a nice touch. I have to say that the Nokia presence was well done--the kiosks and demo phones in this context was a very effective way to reach out to this audience. I'm almost ready to ditch my iPhone (but not quite)...
The whole second floor was also a good place to have ad hoc meetings.
