There are dozens of reasons why Sonos is a vastly different beast than the setup you described. Not the least of which is easy of use and quality of audio. Sonos can play most anything you throw at it (including FLAC which many people who care about audio quality tend to use). I have my Sonos setup with a NAS so my computer is completely out of the equation. I also have a fairly large collection and Sonos makes it a breeze to navigate and easily access music and play multiple streams in different rooms, or easily link them to play together. You can also access Rhapsody over the air (no computer required) which is a fantastic all you can eat program, as well as Sirius, Pandora, Internet Radio, etc... It's by far the best addition to my home media environment in years.
As for this app, well, I still haven't had much of a chance to test drive it but it is VERY limited in functionality. It took an hour or so to index my library.
You can basically select a zone and then select either an album or track to play. You cannot access anything other than your actual library (nothing from the services menu such as sirius or pandora), you cannot link zones, and most importantly to me, you cannot see the "artist" level of your music library. As someone with a fairly large library, that is my typical browsing path as I have too many albums to easily navigate just at that level.
It's a welcome first effort but I sincerely hope the developer is up for refining and improving this with future releases.
