From all the previous reviews I expected the installation to be super-smooth, and everything did work right away, EXCEPT for streaming music from my iMac to the Zoneplayer: the radio streaming and the music services (Pandora/Rhapsody) were streaming flawlessly to the Zoneplayer (via the Zonebridge) because the Zonebridge talks directly to the internet. However streaming music from my iMac to the Zoneplayer was a different matter: whenever I was trying to setup music library in the Sonos desktop software, I kept getting strange errors like "could not connect to <ComputerName>", or "<ComputerName> not found". Then I talked to a Sonos technical rep, and he pointed out that I was having problems because my iMac is on WiFi (i.e. not directly connected to the internet via an ethernet cable). When I changed my setup so that my iMac was connected directly to the internet via an ethernet cable, I was immediately able to setup my music library for streaming. Somehow, somewhere it should have been clearly stated that the computer that hosts your music library MUST BE ON A WIRED connection to the internet, NOT WIFI. Other than this, I have no complaints whatsoever: it has quickly become one of the most-used gadget in my NYC apartment. Most FM reception here is crap, so it's great to have access to all sorts of internet streaming radio stations, plus you get Pandora and Rhapsody. The sound is definitely great for my living room and bed room. And best of all, of course, I can control this from my iPhone. We listen to a ton more music (and more often) just because we have the Zoneplayer. My wife was initially dismissive that I bought "yet another gadget", but when she realized all the things you could do so easily with it, she was quickly converted.
