Pros: Great Open Source Community, Terrific D-to-A
Cons: I guess iTunes DRM, but hey, that's going away, too.
Summary: Ok, first and foremost, the user "ro53ben" above is a longtime Sonos advocate and big contributor on the Sonos forum, so consider the source (google "ro53ben sonos").
For me, it was between the Squeezebox and the Sonos. Sonos is closed architecture and yes, awfully expensive. The Duet (which I received today) will replace my Squeezebox3. It's the perfect choice for my whole-home audio system. I just need one source to replace my 200 disc CD changer to provide music throughout the house. This fits the bill. The UI is great, bright and responsive. The setup was easy, and I'm very happy.
The Duet is $200 less than the cheapest Sonos alternative...oh yeah, you have to pay $40 extra for the Sonos charger. Add the open source community to the mix with the great plugins availabile, and it's a winner.
