Just up on the Google Press Center page is a link to the webcast and a text transcript of Larry Page's keynote address at CES last Friday night. The video/audio and text transcript only contains Larry's remarks from the podium and none of Page's interaction (News.com said it was the highlight of the program) with Robin Williams which is not available due to copyright restrictions. However, you will see (or read) appearances by NBA star Kenny Williams and CBS top gun, Les Moonves.
One highlight is a demo of Google Earth for automobiles that they're working on. Additional coverage of the keynote along with a link to a post keynote news conference is available here.
Also, if you're looking for more presentations by Googlers, this page has links to several.
