Add IAD to set of regions and that it is the default region.

No description provided.

This is not necessarily true. The default region is specified by the API response (resp["access"]["user"]["RAX-AUTH:defaultRegion"])

For me it is DFW.

[nedrocks]

That makes much more sense.

I don't know what this should say to be less confusing but I wasted about an hour trying to figure this out earlier assuming that DFW was correct.

There are also HKG and SYD datacenters, and who know what may come in the future. I think it would be best to list a few example DCs, and include a link to http://www.rackspace.com/about/datacenters/ for current complete listing.

Thanks for the review!

@sivel I've changed the default to explain that it's dependent on account settings.

@EdLeafe I've added a link to datacenters in the documentation.

Hmmm... now that I'm re-reading the whole thing, there are a few other problems. I'll merge this and then fix them myself.
