Matching its Apple TV and Mac Mini brethren, the new Airport Extreme comes in a compact boxy shape. The big news however is that it supports the 802.11n protocol for data transfer speeds that blow 802.11g away. So you can finally order your upgrade to your existing Airport Extreme. Of course you’ll have to have an 802.11n compatible Airport card in your machine to take full advantage of this new hardware. It’ll ship in February for $179.
