Given the word "dock" in the product name, there is a spot with a 30-pin connector ready for an iPhone or iPod, and there is a USB port somewhere as well. But why bother connecting any devices when you can use AirPlay and wirelessly stream music anywhere in your house using iTunes?
Just make sure the PC or Mac has iTunes 10.1 and the iOS device has at least version 4.2 installed. (Don't forget about that iOS 4.3 update, which might drop as soon as today!)
Some of the fun features on this speaker (which looks oddly reminiscent of those discs in Tron: Legacy) include 360-degree acoustics, a small color screen that displays album art, digital FM radio with 10 station preset slots, a dual-alarm clock function and plenty of playback control buttons on the On Air dock itself.
Pricing hasn't been announced yet, and neither has an exact release date. The most revealing JBL has been about launch plans is that we'll see this speaker dock in stores this spring.
