Travel router + Wireless speakers + Network extender + Print server. I have an 802.11g AE model right now and mainly use it as my travel router when I visit my in-laws or stay in a hotel. Plus you can hook up speakers to stream iTunes music (check out AirFoil if you're into that, for multiple AE support), extend your wireless network, and share a printer (nice if you have a laser in the hallway or something). We plug it into the stereo in the kitchen to stream music while we're cooking. Plus it's palm-sized and plugs directly into an outlet, so it's very portable.
The downsides are that (1) you can only have up to 10 users on wifi and (2) you have to use Apple's special Airport Admin software to access the router. The users can add up pretty quick depending on your network (desktop, laptop, cell phone, gaming console, Tivo, etc.). It's a small hassle too because you can't just login from a webpage, you actually have to install their software on every machine that you want to configure the router from.
