Sonos Play:1: Mini Home Speaker (Refurbished) - $99

Sonos Play:1 has been discontinued and will receive no updates. They say bugs will be fixed though. below concerns from Techradar:

If you have one of the affected Sonos speakers, you won't be able to take advantage if the brand introduces any new features or services to the rest of its lineup. For example, if a cool new music service to rival Spotify comes along, your older Sonos speaker won't be able to support it. See

While that's probably not a huge concern to owners of the original Sonos Play:1 and other affected devices, it could prove a problem for anyone who uses one of these speakers as part of a multi-room setup.
This could stop your newer Sonos speaker from receiving the updates it needs; the solution of course, is to disconnect the offending speaker (but then your multi-room setup will be missing one component, which isn't ideal if it consists of only two speakers to begin with).
There's also the possibility that changes from service developers like Spotify or Tidal, that require an update from Sonos to work, could render your old Sonos speaker unable to use your favorite streaming platform.

That was in reference to the rollout of the S2 platform and the S1-only products getting left behind. These Play:1s are compatible with S2.

S2 was released less than a year ago. I think it'll be awhile before Play:1s get left behind. The first speaker model (gen 1 Play:5) was released in 2009 and only got left in S1 last year. Their connect and amp products were even older than that.
