On the Nokia Qt blog is a recap from some of this development conference in Unterschleißheim. There were many Nokia N9s mobile phones that were given away, a keynote by Canonical's Director of Engineering about the Qt-based Unity 2D desktop, and how the CNN news company sees mobile devices within its overall strategy. There was also a "Qt-toberfest", but no word if Augustiner was served at this dinner/party. There's also various pictures from the event in that Nokia blog post and an earlier blog entry.
The slides from the sessions that I have been able to find on the Internet so far include:
Targeting Android With Qt
The Anatomy of Real World Apps - Dissecting cross-platform apps written using Qt Quick and C++
More information on Qt Developer Days 2011 in Munich is available from the Nokia web-site. Coming up at the end of November in San Francisco is another Qt Developers Days event.
