Apple has just updated the small AirPort Express with 802.11n wireless. For those who do not know the difference, the n spec is faster than the g spec — up to being able to wirelessly stream HD video without any network stutters. The new AirPort Express maintains all previous functionality, like the AirTunes music sharing, printer sharing, and easy wireless expansion if you already have a wireless network installed. It is available for purchase immediately through the Apple Store, and has a $99 price tag.
