I've been waiting ages for this release. However, everyone else has caught up and the market still doesn't really care about audio quality. So buy in outside of personal use seems low at this point. So it's a wait and see.
I got them in this week. I never cared much for a usuable audio system in our home. But since we have them as an introduction to the SONOS ecosystem, we're quite in love. Great music now plays in our home all the time. Reducing our time watching TV or browsing on our phones. This being a monthly subscription made it great to just get started. Hopefully I can expand my subscription to other rooms by simple add-ons soon...
