In case you missed his post earlier, Mike Chambers recently uploaded a video of Chris Brichford's MAX preso on how HTML/JS development will be in Apollo. As I was getting a ton of questions at the conference on the subject, I really recommend checking out this ~40 minute video for an excellent overview - Chris not only covers the high-level questions, but some great examples and deep dives into Apollo development. To be clear- the session centers more on HTML via Flash, but as Mike noted earlier you will of course be able to build purely HTML/JS applications in Apollo 1.0, should that be your bag. Great stuff, give it a play.
Those rooms made everything red! Ack...
Now a podcast with slides would be better but that is cool. Thanks for posting.
