Looks like iFilm has all of the Super Bowl commercials available again this year. You can view them with Real, Windows Media Player, or QuickTime, although the highest resolution for Real requires a subscription.
Personally, I liked the Bud commercials http://www.mentalhealthupdate.com/ (especially Sleigh Ride) the best. Budweiser.com has this year's ads on their web site as well. Bud Light took top honors in the USA Today Ad Meter with their “Good Dog” spot.
