We have assembled a sample slide deck that introduces Xamarin 2.0. It's based on a talk that Michael Hutchinson recently gave at a user group meeting. It could be a useful resource for speakers who want to do an introductory Xamarin presentation. You can repurpose it as needed or use it as a starting point for your own slide decks. If you have any other similar material or demos that might be useful, please consider sharing them here.
