Apple officially introduces the AirPort Express with 802.11n today. We have reported over the weekend that the 802.11n AirPort Express leaked in Switzerland.

The early leak might have Apple motivated to release a new product on Monday instead on their favored release Tuesday.
Apple calls the new Apple AirPort Express the world’s smallest 802.11n-based mobile base station, the new AirPort Express offers a great option for anyone who wants to set up a high-speed wireless network, share a printer wirelessly, or stream iTunes music wirelessly from a Mac or PC with AirTunes.
And because it is that compact you can take AirPort Express with you and set up an ad hoc wireless network in your hotel room. Available immediately for Mac and Windows, AirPort Express sells for $99 on the Apple Store.
