I suspect a lot of this has to do with perception. Even though a phone or laptop may appear to be in fine condition after several years and may even work very well, we understand that the internals no longer support more advanced, current hardware and software capabilities. But I don't think the same way about speakers. The part that really matters for a speaker is the construction of the cabinet and the quality of the actual speakers (woofers, mids, tweeters, etc.). Traditional speakers have very little electronics involved. Too bad Sonos didn't design a more modular/swappable system. I can understand needing to replace a central receiver/hub on occasion to take advantage of new capabilities, and/or swap out a component of the speaker, such as a bluetooth receiver. But to make all speakers in a system no longer supported is hard to understand.
