So I bought an Airport Express about a month ago, with the plan to provide wireless music to my new deck. I was never able to get it work... each time iTunes tried to connect to the Airport Express, it would fail. But not today! I decided to give it another chance, now that I had some time. New firmware was available (following recent updates to the AEBS and Airport Utility, it would seem). Updated. Tried it. It works! Now my 16 month old daughter is dancing to Marvin Gaye on the deck on the 4th of July. God Bless America!
