Sonos--deal killer

I don't post much, but I do lurk. Just got my Sonos ZP90 yesterday and went to install it today. BIG suprise, you have to buy another ZP90 or Zonebridge to make the thing wireless over the network, it has to be plugged into the router directly. Went back to the web site and they do have one sentence that does say that you have to have another device (missed it completely). This really needs to be emphasized on their website, they don't seem to have any problem emphasizing the wireless feature of the ZP90. It's a shame, I was really looking forward to trying the Sonos, but I won't even be able to try the thing. I don't have a computer anywhere close to my stereo system, and I'm not about to unplug everything I've got and move it up another floor just to hear how the thing works. I thought the industry standard on wi-fi devices were that they were self contained and would connect to the network without any other support devices. I may be wrong on this, but I have never encounterd another wi-fi device that needed this. I know, my bad, should have paid more attention to the fine print, now I'm out $34 shipping (here and back), but I am not going to pay another $100 on top of the $349 that the ZP90 cost so that I can connect to my network. Sorry about the rant, but if you are looking at the Sonos, be aware that a ZP90 WILL NOT connect to your wireless network without spending another $99. Now to try the Squeezebox Duet.
