Califone launched a $999 PA419 Wireless Portable PA System that’s integrated with an Apple-approved iPhone/iPod docking station. With its integrated 30-watt (RMS) amplifier, the functional 16-channel PA419 is designed for audiences of up to 300 people in rooms up to 2,000 sq feet in houses of worship, meeting/conference rooms, gyms, dance/dining halls, tradeshows and outdoor parties. It weighs just 14.6 lbs.

Although not an earth-shattering announcement, it is a good idea as most music sources are iPhone or iPods. You can see more about it here: http://www.califone.com/products/pa419.php
