Why is is taking so long for companies like iHome or even Apple for that matter to implement a decent, cost effective multi room AirPlay speaker system? iHome's website has said for months under the IW1 AD that they will "email you when it becomes available".http://www.ihomeaudio.com/discover/airplay/ Ok, great, but you guys have been saying this forever. I would like to buy three; for the kitchen, bed/bath, and back porch. Sonos is an option but is a separate system from Apple's AirPlay and is IMO WAY overpriced! Are there any options available that use AirPlay that are out right now?
