We couldn’t agree more. If you are gonna drop a bill and a half on a wireless router (3 times the price of the capable base G models) you are gonna need a reason. Gigabit Ethernet is a differentiator. So is FAST wireless speed. The other routers didn’t seem to offer much of a wireless speed increase – especially at significant distances with interference and regular ethernet speed. The USB Hard drive/printer port also helps – though its reliability is still not up to Apple spec.
We are still a bit on the fence on when to update as some of our devices aren’t N capable and we won’t be able to enjoy the N only mode that shows the best speeds. If we were in the market for a new wireless router today, however, the Airport Extreme would be at the top of our list.
