It may not bring the thunder like an Apple iPhone
but the Airport Extreme does bring draft-N of the 802.11 WiFi standard. That means up to 5x the speed and 2x the performance of traditional WiFi networks which should deliver a bit of a rumble to the living room or office. It also support legacy 802.11a/b/g giving it full 2.4GHz and 5GHz coverage. It also features AirPort Disk, a USB host port around back allowing you to share an external USB hard drive over your wireless or wired network. Or just attach a USB printer and share that, your choice. Best of all, it should work with the unannounced, but apparently real, 802.11n draft hardware in your recently purchased
Mac -- look for a software update to roll soon. By February anyway, when the Airport Extreme ships for $180.
