Apple has quietly upgraded their WiFi router line, releasing the AirPort Extreme. The main feature of the new model is that it features 802.11n wireless, which provides twice the range and five times the speed than 802.11g. The unit is 6.5-inches square, and 1.2-inches tall - but seems to leave a bit to be desired. For instance, there are only three ports for connecting other devices to the AirPort extreme, while most other routers have four. Also, the ports do not support Gigabit ethernet, which is another downer for a product using the term “extreme” in its name. On the plus side though, it does have a USB port for connecting a USB printer or external hard drive. The best part though? It also comes with an 802.11n Enabler, which unlocks the 802.11n capabilities of the newest iMac and MacBook Pro models, which shipped with WiFi cards capable of 802.11n speeds. We suspect you simply run the Enabler, and your Core 2 Duo iMacs and MacBook Pros will fly. The Airport Extreme Base Station ships in February for $179.99 USD.
