Bossa '09 was great, a lot of good old faces around but also some new 'troll' faces. For those that missed any presentation we plan to make them available here or subscribe to the RSS feed here.
Here are some of the available presentation that I recommend:
Elementary – small, scaleable touchscreen widget set for mobile devices - Rasterman
Making videoconferencing easy, also in your application - Olivier Crete
The future of Qt - Thiago Macieira
