Overall it was a great talk, and a pretty good introduction to very foreign subject matter.
The only complaint I had was with the last section on cross-browser testing. Going over the importance of cross-browser testing and highlighting tools is great, but you went into the technical implementation details of using the tool. Since we weren't following along and doing it ourselves, it really doesn't do us any good to know the configuration options - that you said were available on the site anyway. Quick highlight of cool features and letting us know that we can try it out in our own time would have kept the pace higher and more interactive.
