CoolTechZone.com posted a review on the Sonos BU80-ZP80 Digital Music System

We evaluated the original Sonos digital music system back in mid-2005, and needless to say, we were amazingly impressed with a newcomer that made working with digital music systems so easy. Sonos is a prime example of how responsible companies should understand a problem and then work on a solution to remedy them. Think of Sonos as the Apple of consumer electronics. The ZP100 and now the ZP80 are both built on simplifying the consumer experience with simplicity and reliability at an "affordable" price tag.
