The Airport Express is the world's first palm-size wireless base station. The small, lightweight and compact device brings the Internet to every room in your house, all without cables. It also allows you to print wirelessly and has the ability to stream iTunes music to any room in the house. It is compact enough that you can take it with you to create a wireless network on the go. An internal universal AC adapter allows you to plug the Airport Express directly into a wall without extra cables or a power supply. With its modular design, a power cord can be quickly added and plugs can be easily changed for worldwide compatibility.
