The presentation was about the lessons we learned during the development of our Windows Phone 7 application, FeedTso.
On the same topic, Daniela wrote a blog post titled What I learned designing my first Windows Phone7 app, which contains more or less the same contents of the presentation.
As last note I just want to thank Katrien De Graeve and Tom Crombez for having organized this really wonderful event which is the Web Café. I this is a really great format: quick presentations, case studies, and lots of networking and lots of fun. I hope they will keep on doing it even in the new FY.
