I currently have ATV v1 and an airport express. From my iPhone and iPad I only get the option to stream to my AE which I'm already fked off about. Let's say i fell into apples obvious trap of buying a new ATV... Am i going to see an option to stream to multiple speakers? Obviously i can't test this with my current setup.
What started as an exciting new feature has turned into a big steaming turd.
MacBook 2ghz, Mac OS X (10.6.4), Airplay audio from iOS devices on old ATV now!!!
