AirPlay got launched with the new iOS 4.2 and iOS 4.2.1 for iPhone and iPad. This means that you can stream wireless sound and video to any AirPlay enabled device (like an AirPort Express or Apple TV). With this cool little thing from PhotoFast called the AP 1000 you can alo get AirPlay in your car (sound only though). It’s a bit messy to implement, but it’s really cool. I guess that many car manufacturers are planning to us pre-installed AirPlay units when the cars are shipped from the factory. Check out the video below.
