Parece que si accede a Pandora y más cosas por ethernet, además de incorporar el airplay de Apple lo que parece muy interesante para envío de sonido de forma inalámbrica (y supongo que incluso desde el propio ordenador con el Airplay incorporado en el AirTunes).

The Ethernet port lets you stream audio from online music services, such as Pandora, Rhapsody, and Napster, as well as from your home network.

Additionally, built-in AirPlay allows you to stream music wirelessly from your iPhone, iPod touch, or iPad.
You can also access Internet radio stations with the built-in v-Tuner. The built-in HD radio delivers FM that sounds almost as good as CD, and AM that often outperforms conventional FM.
