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.
Onderhoudende leerrijk presentatie, meer moet dat niet zijn.
