Is the Sonos Play:3 just for music or can you stream your TV, Wii and/or regular Macbook (non-music) use through it?
Interestingly enough, the Sonos Play:5 (formerly S5) does have a line-in jack. So you could potentially use that as speakers for other audio sources, but you still have to manage the playback of the line-in jack through the Sonos app. It might be overly cumbersome for this sort of thing.
