But that doesn’t mean the phone can’t make an appearance or two. Speaking at the VentureBeat Mobile Summit in Sausalito on Tuesday, Nokia’s Hans-Peter Brondmo demoed the Symbian-powered device and its impressive picture-taking abilities.

Brondmo showed off a few pictures he has taken, including one of the San Francisco Bay Area, one from a ski trip and another, taken from a plane, of Greenland. In each case, Brondmo said he was able to later focus on things he didn’t even know were in the picture.

“You can really change the nature of photography,” Brondmo said.

Of more relevance to the crowd, Brondmo also showed off the Lumia 900, a high-end Windows Phone which goes on sale from AT&T in the coming days, for $99.

Brondmo also made reference to the attendees, who earlier were divided into Android and iOS camps during a discussion on the mobile-platform wars.

“Are we still Android and iOS, or is this the Windows Phone crowd?” Brondmo said, noting that he hadn’t picked either market share leader during that debate. “I was in the middle of the room, by the way, standing in the back, jumping up and down.”

As for that Windows Phone effort, Brondmo noted that there are now 70,000 apps for Microsoft’s operating system.

“The app ecosystem is voting with their feet,” Brondmo said. “Of course, we are supporting them as well.”

Next year, Brondmo joked, the conference will have to be split into three — a big one for Windows Phone and two smaller ones for Android and iOS.

“We’ll see,” said onstage interviewer Devindra Hardawar.

On the last leg of my trip to Europe to check out Web 2.0 companies, BoomTown spent the day at the Royal Society in the tony environs of St. James’s Park and Pall Mall, for some more lively discussions with more students, academics and entrepreneurs in England.

The Royal Society, by the way, is an “independent scientific academy of the UK and the Commonwealth dedicated to promoting excellence in science.”

In other words: Geek Central of London for more centuries of nerdiness than you can shake a powdered wig at (and, let me just say, there were a lot of powdered wig-wearing techies back when).

As I have written, it’s been a really interesting visit here overall, first at Cambridge University and now here, where a group of entrepreneurs, academics, execs and venture capitalists from Silicon Valley have been mingling with British students, academics and tech entrepreneurs.

It’s all been organized by Ellen Levy of Silicon Valley Connect and U.K.-based tech entrepreneur Sherry Coutu, in partnership with the National Endowment for Science, Technology and the Arts.

So here’s my final video of the events, including interviews with European VC Saul Klein of Index Ventures, as well as Silicon Valley visitors Hans Peter Brondmo of the start-up Plum and Emily Melton, a VC with Draper Fisher Jurvetson.

The conclusion: It’s a small world, after all, as you will see. Also a message from the Queen:
