I loved the keynotes at PDC this year - although as I was trying to edit the Day 1 keynote from 2.25 hours to 30 mins for the #MWord event I wasn't loving it so much. That said, the thing about editing is that you really have to listen and get behind the words being spoken.

I recommend the whole of the keynotes for you - particularly Day 1 with Ray Ozzie and Bob Muglia.

For me, most interestingly from Ray Ozzie's keynote was the discussion of "3 screens and a cloud". You've seen this before probably (maybe from @Stevecla), but here Ray said we were delivering on a "single coherent development strategy" in order to develop for that paradigm(watch from about 15 minutes in - oh, and enjoy the "instant seek" of the smooth streaming experience).

In this he defines the components of that strategy as being:

Of course there's a lot of detail in this - particularly as Bob began to drill down into the detail of the announcements. I'm still getting my head around the whole thing. (I know there's a lot, because I was given a 72-page FAQ doc - and that was just for Day 1).

If you're thinking about how to get across the PDC topic areas at a reasonable level then these are maybe the things to think about to begin with:

Sooo much stuff to do. Hope this helps.
