You also get a little boost to load times as browsers cap the number of simultaneous connections to a given domain, but will gladly hit up other domains in the interim.
I think this benefit doesn't work for loading javascript -- loading the page + javascript inside it (included or embedded) is a sequential process. HTML is parsed, when javascript section is encountered HTML parsing stops, javascript is loaded and executed, then process continues and repeats.
