It's no secret. I freak'n LOVE Sonos. I purchased a few Sonos speakers late in 2012 as a Christmas present to myself. As a result, I listened to more music in 2013 than I did in the last 15 years of my life combined. It made for a happy and productive year. It's just so convenient, it's rock solid in terms of reliability, sounds great and it connects with so many music sources, including my iTunes collection and my favorite streaming service, Songza (which btw, via Sonos is ad free and always works overseas in countries where Songza isn't technically supported).
