I realize I am a little bit late on this one, mainly because AU2012 was so excellent (and full of information) that it took me almost a week or over to go through my 'phase-1' filtering of information.
Hats off to my talented friend Shaun Farrell, who was blogging live from AU2012.If you haven't seen his AU2012 blog posts then I highly recommend visiting his blog.
For my AU2012 summary, I have captured it in pictures in a document attached with this post, link below. I highlighted key slides from each classes I attended as key takeaways for me. As others mentioned, the key message was the future is in the cloud!
