Sonos Digital Music system is going to get much needed upgrade tomorrow. For starters, the Santa Barbara company is going to finally release a mac desktop controller, which will make it easier to manage music libraries for mac user. The desktop controller has been a Windows only feature so far. But that is not all. The Version 1.2 Sonos software will have support for Windows Media® Audio (WMA) Internet radio stations and podcasting. Those with mega collections are going to love the new feature, called “Power Scroll” gives you a shortcut for scrolling through large music libraries via a “scroll by letter” feature on their Sonos™ Controller.
