Apple announced Airport Express today featuring AirTunes.
Enjoy your iTunes music library in virtually any room of your house. Share a single broadband Internet connection and USB printer without inconvenient and obtrusive cables. Create an instant wireless network on the go. Extend the range of your current wireless network. How many devices do you need to do all this? Just one.
The new $129 6.7ounce portable device provides a mobile base station for laptop users as well as wireless music network functionality for home users.
Wireless features had been rumored to be "big" coming from Apple.
A new version of iTunes (4.6) to support the new Airport Express basestation is expected this afternoon.
