Well, unlike Kazaa, this doesn't come with any "free and great deals and spyware". It works exceptionally well, almost too well actually. I had a better-than-phone quality conversation with Sov, and he's on 56k plus that he's in the US and I'm in Sweden. Oh, and of course, the fact that it's free makes it even better. Just add my user (Zelaron) if you need someone to talk to. :P
