I have uploaded the slides from the my talk on HTML5 that I gave at ODTUG Kscope 12 last week. The slides include comments and links to various demos. I haven't had the opportunity to clean up the drag & drop file upload demo and I will post that separately when I have some free time.
You can download the slides or go to the Presentations page to see full abstract and download link. If you have any questions, comments, or feedback please feel free to send me an email (email address in slides).
