Google Chrome (the browser) actually does run on Linux. It even has flash and java support now.
I added the chromium-daily repository, and everything is stable and works fine.

By the way, I still use firefox for the most part. Adblock plus is nice.
In gnome, it's possible to bind the keys to the previous/next/play/pause commands in gnome. Then, any media player that supports those bindings in gnome can be controlled with those keys no matter what application has focus. I have no idea how you would do this in Windows, though.
Ah, but you see...this is why you limit your presentation to 12 minutes (20 minutes in certain cases). Then you have an interactive question/answer session for 5-10 minutes (depending on the interest of the audience).
Always draw your curves, then plot your reading.
