It's only http://www.symantec.com/norton360beta/betacenter/n360betadownload.html
yet, but does anyone see what the main differences are between Norton 360 and Windows Live Onecare?

they are both "next generation" security suites. The software is built to take care of all your basic maintenance with security features, system enhancements and backup tools.

The difference will mostly be found in the details, I suppose, and come out over time. For now, all I know is that Norton has a unique feature to offer that lets you store your backup archives online - away from any harm that might come to your own storage places. (Of course, you won't get to put away entire harddisks like that, but anything critical should do just fine.)

It has since moved out of beta stage.

So, I was wondering if anyone has had a chance to try out the final release, then? I, too, am curious to hear from people who've seen it work ...
