personally, i didn't gather much out of this session. it could possibly be because i am more of a designer, and a lot of the talk was a bit too technical. but also, the most overlying theme was "this isn't solidified yet." and "this may change completely" phrases throughout the whole session.
also, since not all browsers support these new features, and the main consensus was that browsers and accessibility tools won't support this until it's more solidified.
my favorite quote from the session:
"use a browser that doesn't suck" (and that was from the speaker from microsoft)
