Where Does Apple Go Next? by Jason Snell. Everyone seems to be missing the obvious as they contemplate streaming audio from an iPod directly to Airport Express – the iPod interface doesn’t have to only control its own hard drive. A WiFi enabled iPod could just as easily have a “choose source” preference to allow you to use it as your remote.
But really where Apple goes next is it allows you to use Airport Express to send your photos from iPhoto to your TV. In this world, the stereo and the TV aren’t separate anyhow, so to make the connection would likely be trivial.
