Sonos introduced the Sonos Controller for iPad today.

The Sonos Controller for iPad is essentially a ginormous remote control for your Sonos ZonePlayers and features:

• Connections to Pandora, last.fm, Rhapsody, Napster, SIRIUS, iheartradio, iTunes libaries and others
• Easy-to-use music interface: Search for your favorite artists by typing on the virtual keyboard and browse through using the touch interface. Simply drag and drop to add to your queue
• Multi-pane view: See your music menu, what’s playing in every room, and what’s in your queue, complete with album art—all at once
• Landscape and portrait modes

The Sonos Controller for iPad will be available for free in the App Store sometime in mid/late August. Of course, you’ll need a Sonos system to use it.
