I have been using a Apple Time Capsule for a couple of years. It makes automatic backups of your hard drive. That way you can have an archive of all of your data and not have to keep too much of it on your computer's own hard drive. The Time Capsule does double duty as an 802.11n wireless router, which your MBA supports. Is this the sort of thing you are interested in?
I once had my Time Capsule setup for Internet access but had so many problems with it, the details of which I can no longer recall, I gave up on it. These days, if I need to backup a file or files while I am on the road, I do it to a USB thumb drive that I keep in my laptop bag. It's not very sexy but it works.

I didn't have too much trouble setting up remote access. I did it by using the cable modem's IP address. My Time Capsule is setup to share a public IP address, which is the cable modem's IP address. The problem was that everything worked too slowly to suit me, so I decided not to use it any more. Maybe I'll try again sometime but the thumb drive kludge has worked quite well for me, far better than remote Internet access network ever did. Anyway, it's a matter of personal preference and I understand why you use it, although I have decided that for the moment at least it's not for me.
It depends on the Internet speed of both the Internet carrier where your AirPort Extreme is and the Internet speed of where you are accessing it from. If you have slow DSL at either, it will be slow. For huge files, it's not nearly as great as being on the WiFi at home... but for files you need, it's no different than downloading from iTunes.
