?If you use iTunes,? writes Eliot Van Buskirk, ?you should consider the AirPort Express.? That?s because the diminutive base station not only ?supports faster 802.11n wireless networks? and ?enables easy printer sharing.? It also facilitates ?quick-and-easy iTunes streaming.? Just ?plug the Airport Express into a wall outlet near your stereo, run a single cable? (analog or digital) ?to your sound system, run the configuration software, and you?re all set.?
