Dear Sonos,
Just once again voicing my utter frustration with the fact that you are intentionally out dating older products. I've seen your Marketing spin on S1 app versus S2 app, but at the end of the day, you are forcing customers who have spent a ton of money your technology into a compromise situation. Use outdated S1 app (how long until you quite updating this??) or spend more money.
I think this is a terrible business practice. Unlike cell phones or computers, people don't invest in larg sums of money in speakers and components with the idea that at one point in the near future they will be obsolete.
I can tell you that if you continue down this path, Sonos as a company will slowly work itself towards being obsolete (out of business). Your competitors will eventually provide better solutions without risks of being out dated or requiring additional money spend.
If you want to make me a happy customer, take my S1 compatible Connect:Amp and offer me a replacement swap with the newer S2 version at no cost to me. Don't insult me with a 30% discount on the new replacement (Amp) that costs $650 plus tax and shipping! That's $500 out of my pocket due to your decision to obsolete my product! Heck, I spent close to that on my original unit - I don’t want to spend the same again because you’re updating your technology.
At this point, my family and friends have all stopped buying your products for fear of this same thing happening again in the future. Honestly, everyone is now just spending money on cheaper technology rather than investing in Sonos.
Please figure out a better solution - your current thinking kind of sucks from a consumer point of view!
