Sure, you probably caught the Engadget liveblog of the keynote, but Microsoft just published streaming video for the keynote given by Microsoft Chairman Bill Gates. Let us know what sorts of interesting things pop out at you after a more careful inspection of the keynote. If the video stream proves too glitchy, Xbox Live's Major Nelson has posted audio-only files.
[Update 1: looks like the video stream isn't quite working yet, despite a note on the official Microsoft at CES blog indicating that video would be available 10 pm PST on Sunday. Keep hitting the link, it'll eventually show up.
