I really like the first part of it (until the 'Real-world O2 usage' in slide 69), since I think I finally documented my key positioning for O2 (Note: the reason why there are a lot of pages is because the "Keynote to PDF" export created one PDF page per slide transition)
In Brazil I didn't made it to till the end, since I did a bunch of O2 demos and run out of time :)
I also did a full day of O2 Training which went very well (the students were new to O2, and by the end of the day they were all trying to figure out where to use O2 in their day-to-day jobs)
