Let me start off by saying I love you guys. I have a Playbar, Play 5, Play 3, Connect, and am looking to complete my Playbar setup with a couple of Play 1's and a Sub soon.
I also have an Amazon Echo and it is awesome. In fact, it's a bit too awesome and I find myself asking Alexa to play music just because if I want to hear a song, all I have to do is ask; I don't have to bust out my phone. The problem is the speakers on the Echo are mediocre at best. I would much prefer the sound to come out of my Sonos system. With the "internet of things" really starting to take off - integration is going to become more and more important.
Amazon Echo has sort of a plugins-type interface called skills. https://developer.amazon.com/public/solutions/alexa/alexa-skills-kit/getting-started-guide
It would be amazing if you guys could create an skill for Sonos. Something like "Alexa, tell Sonos to play *playlist*." or music by _____ or x from pandora.
I've done some searching and this comes up on this forum a lot. I think it's time you started listening to your community. With skills you no longer need much help from Amazon so its on you to keep your customers happy. Please do not start your own voice recognition or anything silly like that. Stick to what you're great at. Just use what is already available and on the markets and integrate with them.
