A slicker talk from a professional speaker (which also brings with it an agenda). However some interesting stuff about moving meta viewport from a vendor hack to a CSS standard, which brings with it a lot more flexibility in terms of defining how you want to use the screen.
Also some interesting pieces on new units of measurement that are relative to the viewport of the device (vh, vw) and for relating an item to its container.
However it lacked any idea on current state of support beyond being flag enabled in Webkit.
