I've been using the product for over a year, and have been by and large happy.
However, when I got back from vacation yesterday, really needing to soak up music, I have instead been soaking up the pain of a mandated update (mac and android both). Once the apps updated, they have been buggy, my entire "My Sonos" on the android was filled with every album in my Amazon collection and I can no longer listen to radio. I'm super angry that I'm not allowed to decide when I update the software; I prefer to let such things 'mature' a bit before updating, as there are inevitably bugs.
I'm also super angry that I'm sitting here typing complaints on the internet instead of enjoying music. I swear computers are making the world worse in as many ways as they improve.
