Esri has shared videos, handouts and demos from various locations from its 2012 ArcGIS 10.1 roadshow titled Transform Your Organization. You can even get a PDF of the certificate of attendence. Slide decks are provided in PDF, too. The one I downloaded was 34 Mb.
Suggestion: I'd like to see more metadata about what some of these things are. I had to download the PDF under Presentation to learn it was a a file of slides. I'd also like to know the size of the file. It's also confusing that some videos are labeled [video] but other content, demos, that are also videos, but not labeled. I think videos have people in them and non-videos are just what's on the screen with audio.
