Google Talk

I think the implications of this are huge. If this catches on, it could easily replace all other instant messengers (and long distance phone calls). It won't be easy, but if anyone can pull it off, it's Google.

Right now it seems to be lacking features, but I'm sure they will add stuff like file sharing and video support (and hopeuflly NOT things like winks, sounds, ads, animations and all that extra crap that the other big IM clients have).
