Apple's AirPort networking products have a few built-in advantages. First off, they're high quality - both in terms of functionality and in terms of build quality. Secondly, they're simple. Very simple. With the AirPort Utility on a Mac doing most of the heavy lifting, they're basically plug-and-play. In my experience, that is somewhat unusual. We've been very happy with our wireless network, which has a Time Capsule as the primary router, and multiple A1264 AirPort Express devices extending the network. So why am I updating my AirPort networking components? Why rock the boat?
