My opinion probably won’t be popular, but for me the Airport configuration app is a selling point. It’s a simple, sane, nicely designed native app that works wonderfully for configuring either a single router or whole network of routers from a central point, as opposed to having to hop around between each router’s config page. I find it much nicer than most router web interfaces, which are often badly designed and look like they’re stuck in 2005.

What’s more is that the same app works for both my Airport Extreme from 2004 as well as the one I bought two months ago. The consistency is awesome.
