What you have pictured here is the latest Sonos music device. In person the Sonos Wireless Dock is exactly what you were thinking when you read the press release yesterday
. The demo unit had a special Sonos branded half case that left the bottom unaltered, because like many other docks, the cases get in the way of proper docking. The dock does accept the standard iPod dock inserts, so maybe there's still hope that a case manufacturer will ship it with a special insert made with the intent to simplify the life of one who like to use both an iPod case, and a dock together.
Hands on with the Sonos Wireless Dock
