Adding another comment after my one below. I couldn't get the record button (just a keyboard button) and thought it might be because I am in Canada. To test I remoted into our server in Texas and opened the doodle from there... presto, a record button... on IE7 no less. Looks like Google is distributing different versions by region. Why? No clue.

Edit: This works on my Nexus One! Now THAT is cool.
