#1 Thing not on this list - DO NOT DEPEND ON INTERNET ACCESS!
I've seen countless talks derailed by slow or non-existent Internet connections. (Coincidentally the last talk I gave the Wifi was down for everyone). Don't use slides that are only online, and if you need a "live" server interaction mock the server locally or pre-record a screen cap.

Thanks for sharing your experience Rich!
