Since the music system is not with us at the DSL router and we have no wired LAN connection in the living room, the ZoneBridge was necessary. Which is connected as an entry point to the router and allows remote ZonePlayers a SonosNet baptized, implicitly encrypted wireless connection to get to the LAN without having to configure anything. Theoretically, I do that differently. There are so-called WLAN Bridges of other manufacturers who make less money for the same thing and bring non-WLAN hardware into the network wirelessly. If ... In fact, the Web is full of cursing users, do not get their Linksys Bridges & Co. to work correctly, configuration problems or permanent disconnections report etc .. Is the Web also full of help-seeking Sonos ZoneBridge owners? Of course not, the answer to this rhetorical question I have already given. So if I buy me for a sum X problems and hours of troubleshooting, or alternatively, for a bit more money (ZoneBridge) immediate, complete zero configuration satisfaction get - what is in the real sense of the word cheaper?
Sonos is a class of its own and be -zugegeben not weniges- money worth 100%.
[Update 2011-10-04] When I bought the Bridge not quite 2 years ago, she was still twice as expensive as it is today. And even then it was worth the money. At the current rate it is a "no brainer", as we say in English: you do not really need to think and makes the purchase automatically everything right. :-)
