It doesn't offer anything which isn't available elsewhere for less. Indeed, the core feature (routing an internet connection to multiple computers) can be had for significantly less money.
Configuration requires proprietary software. This is of course included in OS X, but if you are using another operating system then you either won't be able to configure it or on Windows you have to download additional software from Apple before you can. Most other routers are configured using a web browser, which to me is far easier.
Lastly, it doesn't include a modem. For me this was the true deal breaker - I would need a modem plugged in and the router, whereas my current router has a modem built in, so I have only one box using up electricity and a power socket.
Unless you have a particular liking for burning money, look at other brands first. You could give the money you save to charity or something.
