Squeezebox Dead?

Yes.
It is.
Migrated to vinyl.

I don't know about everybody else but mine (Touch) is working JUST FINE. I suppose if Logitech shuts down mysqueezebox.com at some point it will restrict its utility. However, it will still stream music from your computer. Sonos is the obvious next choice for similar functionality but I haven't seen anything I would abandon the SB for at this point.

DIY music server using HD-Plex H5.S case, JRiver MC, and JRemote for control. A little clunkier than the Squeezebox iterations, but it works fine for my needs. I do enjoy being able to view album art/info on my LCD TV rather than the tiny screen on the Touch.

I'll probably keep my SBs until they are ready for the audio gear graveyard, which could well be for a while. Everything still works great. I have started to research and experiment with alternate, broader A/V technologies, mainly XBMC running on Android media devices. Usability features continue to improve and may be the ultimate draw to another platform. As long as I am running an external DAC with a good digital connection from source, I am not too concerned at this point about sound quality of devices geared towards a broader market than the very small niche high end audio market.
