Also the microJukebox will autoconfigure itself with Sonos. I know most people will eventually figure out how to enter a cryptic network URL into the Sonos thick client but the microJukebox will just "show up" under the music library.
The microJukebox also has Squeezebox server and a DLNA server so you can access your music from other network music devices like a DLNA home theater receiver or appleTV. Plus other built in app like Plex Media Server let you play music to devices such as Roku.
microJukebox can also transcode your entire music collection from FLAC to mp3. This is good for portable music players, iPod, and car audio players.
So far from a "one trick pony" the microJukebox is more like the Swiss army knife of audio.
To answer Mullig70's question Small Green Computer, the makers of the microJukebox, offer great tech support via email or phone.
