Onderhoudende leerrijk presentatie, meer moet dat niet zijn.
Great talk: detailed but not "too" much, entertaining, and even featuring a *working* demo. The presentation was also very smooth and well-thought.
For future talks you could use the examples to tie things up a bit better: they could follow a "story" (e.g. building a particular set of features) and that would help illustrate the big picture slightly better than with isolated examples for each feature. But even without that it was still VERY understandable.
