Sad to say, this was a side-grade as much as an upgrade, as we’ve lost the ability to play music in our living room without turning on our television. The Airport Express can be selected as an output device directly from iTunes on the computer, without requiring any messing around device-side.
For most people, having to turn on the TV to play music is no big deal — it is, after all, called the Apple TV. However, we have a projector in our living room, and the screen pulls down in front of a big glass door to our balcony, so it’s normally retracted. Furthermore, in daylight it’s tough to see the screen unless we close all of the other blinds in the living room, too. Therefore, to use the Apple TV to play music, we have to close three blinds, pull down the screen, turn on the projector, and wait thirty seconds or so for the projector to be ready. Which means that, right now, it’s easier for me to shamble to the other side of the room and dig through seven-hundred-plus CDs to find what I’m looking for.
I hope that a near-term software upgrade for the Apple TV enables the Apple TV as an alternate output device, as one can do with the Airport Express.
