On the contrary. Their S1 platform started in 2005. They continue to produce great new products with S2, yet S1 stuff continues to function, it just runs ships-in-the-night for those of us with both. Frankly, I'm amazed and impressed they retained compatibility for as long as they did. I have other electronic devices in my possession with such functional longevity, but I can count them on one hand, and none of the others try to perform anything remotely so sophisticated as a Sonos player does. These allegations of being intentionally malicious / consumer hostile don't stand up to scrutiny, nor to comparison with known examples of planned obsolescence in consumer electrical, such as Canon inkjets or Bosch kitchen appliances.
