The Sonos app for iPad is far better than I could have ever imagined.  The iPad’s large screen makes for a wonderful landscape when navigating your multiroom audio system.  It’s clear Sonos took their time with this one.  Select music from any source, build a music queue and receive metadata, including artist profiles, all from a single screen.  This is unprecedented for anything I’ve seen in this price range.
Pair this with our in-wall iPad charging dock station and you have yourself one killer multiroom audio system.
